  • Receiving data from a USB device in C or C++

    - by Midas
    It starts to bore me that I always have to ask questions about trifles. I simply need a list of all plugged in USB devices and have the user select one to let the console application receive any data the USB device sends. I can then start playing around with the data in my program. I don't want to use library's, only standard C++ functions, and the program should work in Windows 98.

  • How do I 'see' an external USB drive connected directly to my Broadband Router?

    - by The Cougar Kid
    This is a very frustrating problem! I have a small home network with several dual boot Ubuntu / Windows computers. I have recently upgraded my Broadband connection and the new router permits the direct attachment of an external USB drive which can back up all of the household's computers. There are no problems when booted under Windows, and there were no problems with older versions of UBUNTU, but since upgrading to 11.10 I can no longer "see" the drive. I used to find it via Network / Windows Network / Home / name of Router, but under 11.10 the same method yields an error message Unable to mount location Failed to retrieve share list from server. Can anyone help please?

  • Dell Latitude will not boot after fresh Ubuntu 12.10 installation. Black screen

    - by James
    I have an old dell latitude d610 that I've just installed ubuntu 12.10 onto, and now unfortunately it will not complete booting up. The screen flashes purple but then fades out and dies. I'm fairly sure there is an issue with graphics drivers, as I had to turn on "nomodeset" in the options when installing off a DVD to see the installer, but I'm very new to linux and don't know terribly much at all apart from what I've read on the net. I have been able to hold down shift and bring up GRUB, and entered into recovery mode, and when I enter into the low graphics mode, the xserver log file says it can detect a screen but found none with a useable configuration, then goes on to say a fatal server error has occurred and no screen have been found at all, telling me to check a log file at "/var/log/xorg.0.log" I have no idea how to check this specific log file! Attempting to actually go further than this in low graphics mode and restart the display simply artefacts the screen. It is all very strange and annoying because I did once by random have the machine boot completely for no apparent reason, but upon restarting the issue reoccurred.

  • How do I remove my Windows 7 setup from a Windows/Ubuntu dual-boot?

    - by Tom
    Previously my OS was Window 7 and some day it began to show problems with booting and finally it didn't boot at all. I tried to repair it but it didn't get repaired. Then I installed Ubuntu 14.04 LTS alongside Windows and am impressed much by Ubuntu. So I want to remove all my Windows files. I searched Google to know how to do it and I found OS-Uninstaller. I have some doubts before proceeding with OS-Uninstaller - I need to keep my photos, songs, movies and personal files in my system even if Windows is removed. Normally Windows files are installed in the C Drive. My personal files are not in the C Drive. So will removing Windows files affect my personal files ? Did the OS-Uninstaller affect Ubuntu anyway ? Please note that I want to remove only the Windows installation files(the files added to my system by Windows during its installation). I don't want to change the NTFS partition to any other format since there is a probability that I will install newer version of Windows later.

  • Dual boot :Windows 7 partition deleted after Kubuntu 14.04 install...Weird!

    - by user292152
    I've bought two new SSD's in order to install Kubuntu on one and Win 7 on the other one. Before I had Linux Mint and Win7 together one just one SSD. So first I installed win7 as recommended, and then used the guided installer of Kubuntu to install Kubuntu. I selected the second SSD, chose the option "use entire disk and install", but to my surprise after rebooting and selecting win7 boot loader from grub2, I got a prompt that my windows installation is damaged, and I need to run the repair option from the installation disk. So I booted into Kubuntu again, fired up kparted and saw that indeed my windows partition got deleted, except the recovery partition. I don't understand what happened. I am not new to this topic, and this was not my first time installing Ubuntu alongside windows. I have never ever had that problem. What can I do to make sure this won't happen again, so I won't waste another 2 hours of my life? ?? Thanks a lot !

  • Is it normal for GRUB to take some time (15+s) after I choose what to boot?

    - by zarnaik
    I had been planning to change the background of my bootloader for a while, and finally got to it. Now the black screen I get for quite some time was made clear. It is still GRUB, because the background image stays, while all of the text is gone. Then it just simply shows the Lubuntu loading screen for, usually, not more than 3 seconds. I run Lubuntu 12.10. My question is, is this normal behaviour or is something going wrong, causing GRUB to take longer? Here are the contents of my grub file located at /etc/default/ : # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND="/usr/share/lubuntu/wallpapers/1210-Windmill_by_Ferran_Reyes.png" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" If you need any other information please tell me and I'll do my best to provide it. :)

  • 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...

  • Bootable GRUB partition

    - by MA1
    I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux Then i installed the GRUB in boot/grub Created the grub.conf in boot/grub Following are the contents of each directory in the USB: syslinux/ boot.cat isolinux.bin splash.jpg vesamenu.c32 initrd0.img ldlinux.sys syslinux.cfg vmlinuz0 LiveOS/ livecd-iso-to-disk osmin.img squashfs.img EFI/ boot/ boot.conf grub.conf boot.efi bootia32.conf bootia32.efi splash.jpg splash.xpm.gz vesamenu.c32 initrd0.img isolinux.bin isolinux.cfg vmlinuz0 boot/grub/ core GRUB files grub.conf olpc.fth Following are contents of grub.conf default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu title funLinux kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said No root device found Boot has failed, sleeping forever So, where is the problem? what i am doing wrong?

  • ATI Radeon HD7000 Series (Laptop) - Switch Mode Between ATI & Intel Integrated GPU. Stuck on Boot Screen On Intel GPU Selection Mode

    - by Monkey Drone
    Laptop Specs: HP Pavilion G6-2020SE GPUs 1) ATI HD7000 Series 2) Intel Integrated OS Installed: x) Ubuntu 12.04 (64 bit) i) ATI Graphics Card Drivers Installed From AMD website. Note: Graphics Card Drivers are Working Fine in 3D Mode. It runs a little Hot as it should since its a GPU. Observation) AMD Catalyst Control Centre Lets me Choose If I want to run the system in HIGH-END (ATI GPU) OR Intel Integrated (Better battery life) While I am on High End GPU Choice, Ubuntu works fine. Problem) But when I switch to Intel Mode in the AMD CCC and reboot the Machine. Ubuntu goes into 'Low Graphics Mode'. The problem is not that it goes into low graphics mode, it is completely expected since I am no longer using the ATI GPU but the integrated Intel GPU. Problem starts with the 'Selection' of the options. During that screen, I have no mouse on the screen (even tried plugging in an external USB mouse) & No Keyboard functionality. Thus I am left completely disabled to choose any option and load into Ubuntu. The Only thing I can do is switch to a terminal and enable ATI GPU through command-line and Ubuntu works Fine again. Is it a bug that there is no mouse/keyboard available to me during the startup of Ubuntu when its launched in Low-Graphics Mode? Any suggestions on how to pass through that? My palms are sweating as I write this down because the ATI GPU is really heating up my laptop. I dont want to boot into Windows or keep it around any longer than necessary. Please advise with help and directions. Sincerely, MonkeyD Edit1: The Answer by Celso has helped me switch to Intel, thus giving me sufficient battery power. Kudos to Celso. Now I can at least use my laptop for the time being without having it burn hair off my skin. I am still looking for answer to my original question of, 'why is lightdm not working properly when I switch to Intel GPU using ATI HD7000 series official drivers provided by AMD'.

  • How to backup boot information of a PC's Hard Disk?

    - by Bear Bear
    I just installed Windows 7 on a partition of my hard disk and I'm planning to install Vista and Windows 8 on other partitions on the same disk, and maybe a few Linux distributions too. Before I install other Operating Systems, I would like to backup the boot information, just to make sure I can get back to Windows 7 in case anything goes wrong with the booting data. I already made a backup of the MBR using MBRFix but I'm wondering if I should save some Boot Sector from the Windows 7 partition? I noticed that Windows Vista install DVD has a "bootrec.exe" utility in the recovery console (Shift+F10) and it has some options to rewrite the boot sector of the partitions. Therefore I wonder if there is any utility (preferably on Hiren's BootCD) to backup/write the boot sector I would also like to know how to backup the boot data of a Linux installation

  • Why would the boot screen be displayed on the external monitor?

    - by hegearon
    Why would the boot screen be displayed on the external monitor? This is not really a problem, I'd just like to know the reason behind this. If I boot without an external monitor both the BIOS settings and the boot screen are displayed on the built-in LCD monitor. However, when I boot with a monitor attached, the boot screen and the BIOS settings are displayed on the external monitor. There isn't any setting available regarding this in the BIOS setup (as opposed to my Thinkpad T42 where there is an option regarding this).

  • How do I make my Boot Camp partition bootable again?

    - by Dan Herbert
    I needed to resize my Boot Camp partition so I used Gparted to move and resize it. This seemed to work, except that now I can't boot into Windows. I can boot into OS X just fine. OS X can recognize the Boot Camp partition and view its contents. When I try to reboot into Windows, however I get the message: No bootable device -- insert boot disk and press any key The only solutions I've been able to find online suggest that the only way to fix this is to either clone the drive or remove the Windows partition and re-install it. Is there any way to fix my Windows partition so that I don't have to reinstall Windows again?

  • Specify next boot to be into safe mode/WinRE via commandline?

    - by TMRW
    As the title says.I would like a script that tells windows that the next boot should be into safe mode or atleast that the "F8" menu should be presented next boot.Booting into WinRE(Launch startup repair...) is problably even more un-doable.I looked over bcdedit options but did'nt see anything like this.I know msconfig has an option for safe boot but it's gui only. Currently if i wan't to boot into safe mode or launch WinRE then i have to forcefully restart my pc first for those options to be presented during boot(F8 does not bring up the safe mode option under normal conditions). Im using Windows 7 x64.

  • Does /boot safe on top of a lvm LV (logical volume)?

    - by fantoman
    Title already asked the question. More specifically, I read in some documents that logical volumes are nice in general but not for /boot in a linux system. They say that bootloaders don't understand LVM volumes, so create a separate partition for /boot out of lvm. I recently installed Ubuntu server (9.10) for my home server, but by default /boot is created in the LVM. Everything is fine now, but I am not sure it is safe to use /boot in LVM. Second question is do I really need a physical partition (volume)(pv) for /boot or is it equally fine if I put it into a logical volume (lv) on top of a single shared volume group. Thanks in advance.

  • Restoring the Windows 7 boot loader after uninstalling Windows 8?

    - by ???
    A while back I installed Windows 8 Consumer Preview on my PC. As expected, I quickly grew bored of it, and uninstalled it. I removed the whole partition on which I had installed the OS, and everything seemed okay, until I rebooted. Whenever I reboot, I'm displayed with the Windows 8 boot loader (even though I deleted the whole partition it was on?), and I can't choose any operating system to boot into. It just says that there was an error. I did some research, and found out that I should use EasyBCD, but I'm not sure if I can burn it on to a CD and then boot from it? (I have only 700 MB CDs available) Or if there's another tool that I could burn on to a CD that would let me remove the Windows 8 boot loader, and just let me boot to Windows 7.

Can anyone help with this? Below is what I have: What I have is the following: /dev/sda apple partitions /boot ext3 (root) ext3 swap side notes: From what I understand, I should have had my boot partition as fat32/hfs+...

  • Installing Ubuntu 10.04 to external HDD overwrites the MBR of the internal HDD

    - by zkrpar
    I have a Asus A42F laptop which has Windows 7 32 bit installed on it's internal HDD. I have just installed Ubuntu 10.04 on a portable HDD using the laptop.

  • grub2 loopback booting ubuntu server iso

    - by Thermionix
    I've got usb-keys setup to multi-boot different linux images using grub2 loopback. The standard ubuntu release isos boot fine, however when attempting to use the server iso it will fail to install saying 'unable to detect cd-media for installation'. the grub.cfg entry; menuentry "ubuntu-12.04-server-amd64" { set isofile="/boot/ubuntu-12.04-server-amd64.iso" loopback loop $isofile linux (loop)/install/vmlinuz file=$isofile/preseed/ubuntu-server.seed ro noprompt noeject -- initrd (loop)/install/initrd.gz } I've attempted to add the following parameters as the fromiso works for debian images on the key iso-scan/filename=/boot/ubuntu-12.04-server-amd64.iso iso-scan/filename=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso fromiso=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso

  • Dual booting Ubuntu 12.04: UEFI and Legacy

    - by cmhughes
    I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :) Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS. Here is what I have found so far: Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at least from the live disk) in UEFI mode I have been able to boot Ubuntu using a live USB disc, provided that I change the Bootmode to Legacy. I haven't committed to installing it yet, because I don't really understand the consequences. My main concerns are that instead of simply selecting Windows or Ubuntu in Grub, I would also have to change my Bootmode every single time, which seems like a lot more trouble than it should be. So, the question: how can I install Ubuntu 12.04 or 12.10 in UEFI boot mode?

  • Where is my problem? The P6X58D Premium Mobo, Windows 7, or other?

    - by Dylan Yaga
    I was having problems with my USB devices for an hour last night, and I am unable to determine the root cause of the problem. The two symptoms are: At seemingly random times (not consistently spaced by time or caused by any detectable event) my USB devices become "detached". Windows will play the USB disconnect sound and then the reconnect sound. The devices disconnected and then reconnected. My USB Keyboard will "stick" on one key for several seconds before processing any other keystroke made. The mouse also does not respond to clicks. I do not lose mouse movement or USB device connectivity. And after a moment of this several beeps will be emitted from the speakers. Hardware Specs: GFX Card: EVGA GeForce GTX 470 Superclocked 1280MB DDR5 PCIe Motherboard: ASUS P6X58D Premium Intel X58 Socket LGA1366 MB Processor: Intel Core i7-920 2.66Ghz 8M LGA1366 CPU Memory: Corsair Dominator 6144MB PC12800 DDR3 Storage: Hitachi 1TB Serial ATA HD 1600MHz 7200/32MB/SATA-3G Cooling: Corsair Hydro H50 CPU Liquid Cooler Case: Corsair Obsidian 800D Full Tower Case Power Supply: Corsair HX1000W 1000W Modular Power Supply Steps I have taken to narrow down the problem: Restarted the computer. - No change Changed USB port the Hub was connected to on the CPU. - No change Removed all devices from USB Hub and connected directly to CPU. - No change Used a different USB keyboard both in USB Hub and directly to CPU. - No change Disconnected and reconnected all cables. - No change Disassembled the Tower and determined if the USB headers were firmly connected. - No change Checked device manager for errors. Checked all USB devices. - Nothing flagged After an hour of frustration trying to narrow down the problem it appeared to disappear. But I am torn between it being a Mobo problem or an OS problem. Is there anything else I can do to narrow down the problem before a reformat and then eventually exchanging the Mobo?

  • Help understanding my hard drive / partitioning situation... Pictures Included! :)

    - by xopenex
    So I have installed windows 7, and two different distros of linux... I have read and tried to understand things like "spanned" "extended" "primary" "swap" "dev/dev2/" "GRUB" "Windows Boot Loader/Manager" etc.... I have a very very limited understanding of all of it! :) I am trying to figure out how to get all OS boot options on one Boot manager (I'm thinking it will be GRUB), because at this point when i turn on my computer, I basically get two booting options (excluding the memtest options etc)... One options is to boot one of my Linux Distros and the second option is to boot my Windows 7. When i go with the first option, Linux boots up... when i go with the second Windows 7 option, I get the "windows boot manager screen" and I can choose Windows 7 or my other installation of Linux (Ubuntu)... In addition, I did not have swap partition from my first installation of Linux, I created it during the installation of my second distro... This is a lot of info for me, but I'm guessing that you linux Gurus, pretty much understand what is going on! Hope my question makes sense.. i will try and simplify... Can i get all 3 OS's optioned to boot from one GRUB? Can i get both Linux distros to use one swap file (I have seen this possible in other threads, but because of how my disk is partitioned, i dont know if i can do this) I hope that i dont have to start all over installing one after the other. Ive got some pics that may help understand my hard drive situation! Thanks guys! :) EDIT... i had some pics, but im a new member.. so cant post them... :( here is a description of the pics... incase i can email them or post later. [grub][3] First Screen I come to after turning on computer... "Ubuntu with linux 3.2.6" (highlighted) fires up Linux perfectly... other choice at bottom of list "Windows 7 (loader) (on dev/sda1)... brings me to the next picture below.. windows boot manager [win boot mngr][6] both options here load the os selected [Disk Manager Windows][1] picture of my hard drive situation through windows disk manager utility [gparted][2] picture of my hard drive situation through "gparted" [mycomp][4] picture of my hard drive situation through "my computer" [paragon][5] one last pic of my hard drive situation through the eyes of "paragon"
