  • USB Device Not Recognized (Mac)

    - by Nargis
    Fortunately, my Mac-pro also made one of my USB storage devices inoperable. My data loss in that USB device but such as another USB device and USB keyboard are unaffected. I have heard that my friend usually trigger this problem by having at least two devices plugged in - typically thumb drives/USB flash drives, and then once a second flash drive is plugged in that become unrecognized. I have only two USB ports and first I think port loose when I connect two USB devices. But later I found these hidden files (“.Spotlight-V100”, “.TemporaryItems”, “.Trashes”, and “._.Trashes”) are created by Mac OS. And before unrecognized that USB device I have deleted these files and my friend had also done the same action. Now I don’t want to test for next USB device to become unrecognized and I won’t deleted any hidden system file inside the flash drives. But I really want to know why these problems happened. Can I delete these hidden files when I only connect to virtual machine (Vista), because I used to delete all useless hidden files from USB flash drives? Any suggestions or thoughts to prevent this or alternative suggestions to fix the problem that take lossless would be much appreciated.

  • Can't remove zfs log device from pool

    - by netmano
    I run a FreeBSD 9.0 server with ZFS pool version 28 and ZFS version 5. I had two pools with a log on ssd's two partitions. These pools was created on FreeBSD 8.2 with ZFS pool version 15, and ZFS version 4. After I upgraded to the new zfs version, I tried to remove the SSD log device from both pools both command was successful (no error message). One of the pools was the log removed, but the other still there, I down the server removed the ssd physically, and hoped it will be forgot by the zpool. The zpool became degraded as ssd was missing. I tied to remove again. No error message, but the log device entry still there. After it, to became the pool online again, I created a file on the root UFS partition and replaced the missing to device to this file. It was successful, the pool again online. However I can't remove the log device from the pool. Where can I have to look for error messages? (in dmesg there is nothing about it, also the zfs remove doesn't have any error message, it's seem like it was successful.

  • 100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

    - by Will3265
    On my server I am trying to install a new usb drive but all that happens is that the system starts using huge amounts of processor cycles with services.exe. On closer inspection with process explorer there is a thread called umpnpmgr.dll using most of the services.exe processor time. I left it for a half hour and still nothing happened. Rebooted and tried again, same result. Tried a different usb drive, then a flash drive but still same issue. Tried updating driver but it said the update function was already in action. I have used process explorer to kill the thread now so the server can still perform its intended functions. Any device that was previously installed before this began happening will still work but any device new to the system will not. My question(s) is/are: Is there a way to manually install the device into the registry so Windows thinks it is a previously installed device? Or can this problem be repaired through anything other than a reinstall? To do a reinstall would mean backing up large amounts of data which is hard with a usb drive and insufficient space on all other network machines. Any help would be greatly appreciated. William

  • Trying to find USB device on iphone with IOKit.framework

    - by HuGeek
    Hi all, i'm working on a project were i need the usb port to communicate with a external device. I have been looking for exemple on the net (Apple and /developer/IOKit/usb exemple) and trying some other but i can't even find the device. In my code i blocking at the place where the fucntion looks for a next iterator (pointer in fact) with the function getNextIterator but never returns a good value so the code is blocking. By the way i am using toolchain and added IOKit.framework in my project. All i what right now is the communicate or do like a ping to someone on the USB bus!! I blocking in the 'FindDevice'....i can't manage to enter in the while because the variable usbDevice is always = to 0....i have tested my code in a small mac program and it works...

    I'm trying to run OpenVPN as a portable application and to that effect i have installed it on a Windows 7 machine, copied the files to another windows 7 machine and manually restored the registry settings using a .reg file. Whenever i try to run open vpn GUI i get the following error error opening registry for reading HKLM\SOFTWARE\OpenVPN I have verified that the key mentioned is indeed in the registry at the correct location with the correct values yet the GUI still complains. I have tried running the gui as an administrator (i'm logged in as an administrator) and also the compatibility modes but none helped.

  • Windows Boot Manager, linking a 'device' to boot linux

    - by TheCompander
    I'm attempting to boot linux on a UEFI-GPT machine with a Windows Boot Manager (WBM). So far I have installed Archlinux (Arch) with Grub. The grubx64.efi is successfully on my windows boot partition and I can see the option to use it in UEFI-BIOS, selecting this loads grub and I'm able to get into Arch fine. I have noticed that in the Windows Boot Manager, selecting from the splash screen, 'Change defaults or choose other options' 'Choose other options' 'Use a device', shows the boot options as in UEFI-BIOS, in my case grub shows as 'Linux'. Selecting 'Linux' reboots the computer and loads grub then Arch. Is there anyway to use this entry for the device 'Linux' to show directly on the WBM splash screen under the entry for Windows 8.1? Ideally i'd like the 'Arch Linux' to link to the 'Linux' device. Guidance with bcdedit appreciated, thanks in advance.

  • Looking for a USB Thumbdrive / Flash drive encryption solution (not TrueCrypt)

    - by Max888
    I am looking for a USB Thumbdrive / Flash drive encryption solution. I have searched the net but I have never come accross a solution which meets the following: Must handle at least 4GB volume If possible, fully portable (no install required required) Does not require admin rights in order to access/write encrypted files on the flash drive Does not corrupt data should the flash drive is removed from a USB port and the data is in a 'unencrypted' status Data is automatically encrypted if the flash drive is removed from a USB port and the data is in a 'unencrypted' status Portable apps must be able to run from the 'unencrypted' volume (in non-admin mode) PLEASE do not mention TrueCrypt as I am not considering (especially for wish list #3) Many thanks! Update 5th October 2009: Still unresolved.

  • Share laptop's Wi-Fi with a LAN connection and a mobile device

    - by xperator
    OS: Windows 7 64bit I want to share my laptop's internet connection between my PC and my Android device. But I can only do one of them at a time. The laptop is connected to internet wirelessly. The PC is connected to the laptop using a Ethernet cable and internet is shared between them. I want to connect my mobile device to my laptop by making the laptop into a Wi-Fi hotspot. PC (Ethernet) == Laptop (connected to net by Wi-Fi) <== Mobile device (Wi-Fi hotspot) I have 3 connections in my laptop: Wireless Network Connection (internet - shared) Local area connection (PC) Wireless Network Connection 2 (Wi-Fi hotspot) Every time I have to disable either the LAN to get the Wi-Fi hotspot working, or disable the Wi-Fi hotspot to get LAN working. How can I share so I can use both at the same time?

  • Dell XPS 15 (L502x) sound problem

    - by lauramolenaar
    I have a problem with my sound on my Dell XPS 15.

  • Bluetooth device won't re-add after being removed (Windows 7)

    - by HericDenis
    I've got a SBH52 headset, it works fine on my android phone, then I tried to use it with my Windows 7 PC, then it won't work because Microsoft Windows dosen't have native support for A2DP connections and one of the answers on the previous link said that removing the device from "devices and printers", running this software and then re-add the device would solve the problem. But the big problem is that they won't pair again: I tried, hopelessly, the suggested fixes from Windows, it won't work. By the way, it is Windows 7 (x64), it just looks like Windows 8. I had this problem once many years ago with other PC and Bluetooth device, I remember it had something to do with drivers that were not removed and I tried to delete them from somewhere, and as far as I remember it worked, but no idea how. In short, how can I pair it again with my PC?

  • Beginner Geek: How to Use Bookmarklets on Any Device

    - by Chris Hoffman
    Web browser bookmarklets allow you to perform actions on the current page with just a click or tap. They’re a lightweight alternative to browser extensions. They even work on mobile browsers that don’t support traditional extensions. To use bookmarklets, all you need is a web browser that supports bookmarks — that’s it! Bookmarklets Explained Web pages you view in your browser use JavaScript code. That’s why web pages aren’t just static documents anymore — they’re dynamic. A bookmarklet is a normal bookmark with a piece of JavaScript code instead of a web address. When you click or tap the bookmarklet, it will execute the JavaScript code on the current page instead of loading a different page, as most bookmarks do. Bookmarklets can be used to do something to a web page with a single click. For example, you’ll find bookmarklets associated with web services like Twitter, Facebook, Google+, LinkedIn, Pocket, and LastPass. When you click the bookmarklet, it will run code that lets you easily share the current page with that service. Bookmarklets don’t just have to be  associated with web services. A bookmarklet you click could modify the appearance of the page, stripping away most of the junk and giving you a clean “reading mode.” It could alter fonts, remove images, or insert other content. It can access anything the web page could access. For example, you could use a bookmarklet to reveal a password that just appears as ******* on the page. Unlike browser extensions, bookmarklets don’t run in the background and bog down your browser. They don’t do anything at all until you click them. Because they just use the standard bookmark system, they can also be used in mobile browsers where you couldn’t run extensions. For example, you could install the Pocket bookmarklet in Safari on an iPad and get an “Add to Pocket” option in Safari. Safari doesn’t offer browsing extensions and Apple’s iOS doesn’t offer a “Share” feature like Android and Windows 8 do, so this is the only way to get this direct integration. You could even use the LastPass bookmarklets in Safari on an iPad to integrate LastPass with the Safari web browser. Where to Find Bookmarklets If you’re looking for a bookmarklet for a particular service, you’ll generally find the bookmarklet on that service’s site. Websites like Twitter, Facebook, and Pocket host pages where they provide bookmarklets along with browser extensions. Bookmarklets aren’t like programs. They’re really just a piece of text that you can put in a bookmarklet, so you don’t have to download them a specific site. You can get them from practically anywhere — installing them just involves copying a bit of text off of a web page. For example, you can just search the web for “reveal password bookmarklet” if you wanted a bookmarklet that will reveal passwords. We’ve covered many of the must-have bookmarklets — and our readers have chimed in too — so take a look at our lists for more examples. How to Install a Bookmarklet Bookmarklets are simple to install. When you hover over a bookmarklet on a web page, you’ll see its address begins with “javascript:”. If you have your web browser’s bookmark or favorites toolbar visible, the easiest way to install a bookmarklet is with drag-and-drop. Press Ctrl+Shift+B to show your bookmarks toolbar if you’re using Chrome or Internet Explorer. In Firefox, right-click the toolbar and click Bookmarks Toolbar. Just drag and drop this link to your bookmark toolbar. The bookmarklet is now installed. You can also install bookmarklets manually. Select the bookmarklet’s code and copy it to your clipboard. If the bookmarklet is a link, right-click or long-press the link and copy its address to your clipboard. Open your browser’s bookmarks manager, add a bookmark, and paste the JavaScript code directly into the address box. Give your bookmarklet a name and save it. How to Use a Bookmarklet Bookmarklets are easiest to use if you have your browser’s bookmarks toolbar enabled. Just click the bookmarklet and your browser will run it on the current page. If you don’t have a bookmarks toolbar — such as on Safari on an iPad or another mobile browser — just open your browser’s bookmarks pane and tap or click the bookmark. In mobile Chrome, you’ll need to launch the bookmarklet from the location bar. Open the web page you want to run the bookmarklet on, tap your location bar, and start searching for the name of the bookmarklet. Tap the bookmarklet’s name to run it on the current page. Note that the bookmarklet only appears here because we have it saved as a bookmark in Chrome. You’ll need to add the bookmarklet to your browser’s bookmarks before you can use it in this way. The location bar approach may also be necessary in other browsers. The trick is loading the bookmark so that it will be associated with your current tab. You can’t just open your bookmarks in a separate browser tab and run the bookmarklet from there — it will run on that other browser tab. Bookmarklets are powerful and flexible. While they’re not as flashy as browser extensions, they’re much more lightweight and allow you to get extension-like features in more limited mobile browsers.

  • Why is my Internet connection randomly dropping?

    - by Jeanno
    Ever since I have installed 12.04 (clean install not an upgrade), i have been having a drop in the Internet connection. The drop in the connection can be anything from 15 seconds to about 3 mins, and then the connection comes back. This behaviour happens while I am actively browsing the Internet, or if I wake up the computer and open Firefox (sometimes I have connection and sometimes I don't) . Please note that when the internet connection is on, it is not slow (as speedtest.net results show) In the beginning, I thought it was a problem with the driver r8169 for my RTL8111/8168B Ethernet card, so I downloaded the r8168 from Realtek website, followed the detailed instructions (blacklisted r8169, changed the file to '.bsh' ...), but still the same problem persisted. So I switched to a wireless connection, and I got the same problem with internet connection dropping randomly. Any ideas?

  • Oracle ADF Mobile and Developing On-device Mobile Applications

    - by Joe Huang
    Hi, everyone: It has been almost a year since we posted to this blog, and I am happy to report that we are steadily marching toward releasing a new generation of ADF Mobile.  This blog site has been quiet as we are heads down to develop this new generation of ADF Mobile.  As we are nearing releasing this next generation product, there are substantial number of Oracle internal application teams and external customers/partners actively developing using the beta version of this framework.  We are actively taking feedbacks from these teams and ensuring the product is ready for general availability. If you are intersted for more details around this new generation of ADF Mobile, we are hosting a session and a hands on lab this week at the ODTUG KScope 12 conference.  The lab is booked completely full weeks in advance, but perhaps you can still get into the session (Wed at 9:45 AM).   Look for updates from this blog site as well as the Oracle OTN ADF Mobile landing page during the weeks leading to Oracle OpenWorld 2012.   Thanks, Joe Huang

  • Xen DomU on DRBD device: barrier errors

    - by Halfgaar
    I'm testing setting up a Xen DomU with a DRBD storage for easy failover. Most of the time, immediatly after booting the DomU, I get an IO error: [ 3.153370] EXT3-fs (xvda2): using internal journal [ 3.277115] ip_tables: (C) 2000-2006 Netfilter Core Team [ 3.336014] nf_conntrack version 0.5.0 (3899 buckets, 15596 max) [ 3.515604] init: failsafe main process (397) killed by TERM signal [ 3.801589] blkfront: barrier: write xvda2 op failed [ 3.801597] blkfront: xvda2: barrier or flush: disabled [ 3.801611] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801630] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801642] Buffer I/O error on device xvda2, logical block 6521396 [ 3.801652] lost page write due to I/O error on xvda2 [ 3.801755] Aborting journal on device xvda2.

This can be seen in /proc/drbd (by "wo:f, meaning flush, the next method drbd chooses after barrier): 3: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---- ns:2160152 nr:520204 dw:2680344 dr:2678107 al:3549 bm:9183 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 And on the other host: 3: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r---- ns:0 nr:2160152 dw:2160152 dr:0 al:0 bm:8052 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 I also enabled the option disable_sendpage, as per the drbd docs: cat /sys/module/drbd/parameters/disable_sendpage Y I also tried adding barriers=0 to fstab as mount option. Still it sometimes says: [ 58.603896] blkfront: barrier: write xvda2 op failed [ 58.603903] blkfront: xvda2: barrier or flush: disabled I don't even know if ext3 has a nobarrier option. And, because only one of my storage systems is battery backed, it would not be smart anyway. Why does it still compain about barriers when I disabled that?

The secondary is software RAID1. Isn't DRBD+Xen widely used? With these problems, it's not going to work.

  • Wireless device not working...supposed problem with b43 driver

    - by Francesco
    I just installed Xubuntu 11.10 onto an old Acer Aspire 3003wlmi. The wireless card is not working. I did all the passages illustrated in the troubleshooting guide but I came up with nothing. It says that driver is b43, but when I booted from the installation cd I noted down some messages saying "Error - b43/ucode " and "Error b43/phy_...something". I had Ubuntu 10.10 installed before and I remember I had similar problems but I don't remember how to solve it. If you please can help me. thanks a lot. Francesco

  • Unmount Mass Storage USB Device from the Command Line in Linux

    - by Casey
    I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output: $ dmesg | grep sd [20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0 [20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error: $ gphoto2 --list-config *** Error *** An error occurred in the io-library ('Could not lock the device'): Camera is already in use. *** Error (-60: 'Could not lock the device') *** What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed. Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.

  • Auto Save and Auto Load Game onto the Device's Storage Concept Question

    - by David Dimalanta
    I'm trying to make a simple app that will test the save and load state. Is it a good idea to make an app that has an auto save and load game feature only every time the newbies open the first app then continues it on the other day? I tried making a sprite that is moving, starting at the center. When I close and re-open the app, the sprite goes back to the center instead of the last coordinate where the sprite land on this part (i.e. at the top). The thing I want to know how the sequence of saving and loading goes like this: I open the app The starting sprite at the center. It displays a coordinate of the sprite plus number of times does the sprite move. I exit the app that automatically saves the game without notice. Finally, when I re-opened it, it automatically loads the game retaining the number of times the sprite move, coordinates, and the sprite's area landed. These steps above are similar, but not the sprite movement test app, to the sequence of saving and loading the game's level and record in Jewel Stackers for the Android app. And, by default, if there is no SD card in any tab or phone that runs on Android, does it automatically save/load onto the internal drive or the APK file itself? Is it also useful to use auto save and auto load feature for protecting and fetching informations (i.e. fastest time, last time where the sprite is located via coordinates, etc.)?

  • GUI device for throwing a ball

    - by Fredrik Johansson
    The hero has a ball, which shall be thrown with accuracy in a court on iPhone/iPad. The player is seen from above, in a 2D view. In game play, the player reach is between 1/15 and 1/6 of the height of the iPhone screen. The player will run, and try to outmaneuver his opponent, and then throw the ball at a specific location, which is guarded by the opponent (which is also shown on the screen). The player is controlled by a joystick, and that works ok, but how shall I control the stick? Maybe someone can propose a third control method? I've tried the following two approaches: Joystick: Hero has a reach of 1 meter, and this reach is marked with a semi-opaque circle around the player. The ball can be moved by a joystick. When the joystick is moved south, the ball is moved south within the reach circle. There is a direct coupling with the joystick and the position of the ball. I.e. when the joystick is moved max south, the ball is max south within the player reach. At each touch update the speed is calculated, and the Box2d ball position and ball speed are updated. NB, the ball will never be moved outside the reach as long as the player push the joystick. The ball is thrown by swiping the joystick to make the ball move, and then releasing the joystick. At release, the ball will get a smoothed speed of the joystick. Joystick Problem: The throwing accuracy gets bad, because the joystick can not be that big, and a small movement results in quite a large movement of the ball. If the user does not release before the end of the joystick maximum end point, the ball will stop, and when the user releases the joystick the speed of the ball will be zero. Bad... Touch pad A force is applied to the ball by a sweep on a touchpad. The ball is released when the sweep is ended, or when the ball is moved outside the player reach. As there is no one to one mapping between the swipe and the ball position, the precision can be improved. A large swipe can result in a small ball movement. Touch Pad Problem A touchpad is less intuitive. Users do not seem to know what to do with the touch pad. Some tap the touchpad, and then the ball just falls to the ground. As there is no one-to-one mapping, the ball can be moved outside the reach, and then it will just fall to the ground. It's a bit hard to control the ball, especially if the player also moves.
