  • bootable USB / installation requirements

    - by Chris Wilson
    Originally asked on One Hundred Paper Cuts Answers thread On the official site: http://www.ubuntu.com/netbook/get-ubuntu/download The instructions for creating a bootable USB key for installing Ubuntu Netbook Remix include a line saying: "Insert a USB stick with at least 2GB of free space" I recently installed UNR on a netbook -- in fact, the one I'm using right now -- and I went ahead despite only having a 1GB USB key on hand. Everything went smoothly and installed 100% correctly. If I had waited to go out and buy a 2GB USB key I would have spent that money unnecessarily and wouldn't have been able to use the computer in the meantime. I was wondering if there's a specific rationale for requiring a 2GB USB key, or if the instructions could be changed to indicate that it can be done with only 1GB. Thanks!

    - by steve
    I got the Ubuntu 11.10 32-bit edition and i used Unetbootin to write the ISO to a usb stick.After that i tried to boot from the stick,having changed the BIOS boot settings,and when the first interface shows up with the choices of istallation,whatever choice i select i got the message"invalid or corrupt kernel image".I use a netbook with windows 7 on it.I tried different usb sticks but same again.I also tried Universal USB installer instead of Unetbootin but same again.Any idea of what happens?I am using ASUS 1000H.The USB doesn't work in one more PC i tried to,but i also tried a second USB to both of the two computers and same again. I downloaded the ISO image once again and follow the same procedure but same again

  • Save to Hard Drive instead of bootable USB

    - by WAM
    I followed the instructions on the Ubuntu website on how to put Ubuntu 12.04 on a USB and make it a bootable USB stick for windows. It worked fine and I can boot up and run Ubuntu, but every time I try to download software or change settings it tries to save it to the USB rather than the hard drive built into the computer. The USB doesn't have enough space so the download fails and in addition it doesn't retain setting changes so when I restart my computer all the settings return to default and anything I saved is gone. Is there any way to change things so that when I download software or change settings Ubuntu will save it to my hard drive instead of the USB?

    I'm running Ubuntu 11.10 (64-bit) as a VirtualBox guest on a Win7 64-bit host. When I plug in my Android Epic4g (Galaxy S) both the host and guest see the device properly, however lsusb does not.

  • Any large USB sticks with integrated card readers?

    - by Al
    I have one of Kingston's DataTraveller Micro Reader USB sticks, a fantastic memory stick with an integrated micro SD and M2 card reader. However, I've gradually filled it to the brim and am looking for a larger stick. Unfortunately, Kingston don't make them any bigger than the 4GB one that I currently have and I was hoping to go to 16GB now that they've come down in price. Does anyone know if any manufacturers make something similar: a 16GB stick with a micro SD card reader integrated (I'm not bothered about the M2 reader).

  • Putty can't connect to USB modem on Windows 7

    - by IanM
    I'm trying to configure caller id on a USB modem connected to a Windows 7 x32 machine. Hyperterminal isn't available so I downloaded the latest version of Putty and am using the Serial option. I'm using the modem's COM port details from Device Manager (COM5, 115200 baud), but when I open the putty session it just hangs with the cursor at the top left hand corner. Hitting the Enter key does nothing. Any ideas??

    I have a Motorola phone, with a MicroSD slot, which my Ubuntu machine does not recognize as a USB drive. It does know there is something there since It automatically charges my phone whenever I connect it. using the command lsusb shows it as "Motorola PCS" Is there a way to tell Ubuntu/Linux that the connected hardware is a disk drive?

  • Pen drive is recognizing as a USB Internet Dongle which connects to the PC. How do the Pen drive configure well in Ubuntu 12.04?

    - by Eranga Fernando
    Every time I connect my Pen drive it recognizes as more like a Dongle. The reason that I'm telling that if I connect it to the PC when I'm on the INTERNET, it will automatically copy all the files which are in the Dongle. So, I can't recognize which one is the Pen drive when I want to safely remove the device. I'm not sure whether it is the Pen drive or the Dongle..? Can anyone give me a good advice how to solve this problem?

  • USB device changes using udev and D-Bus

    - by kicsyromy
    I am trying to get a list of currently plugged in USB devices in Ubuntu 10.10 and monitor changes that happen, like devices being plugged in or out using udev and D-Bus. I'm fairly new to programming using D-Bus. I saw one example: "Linux: How to detect is usb keyboard is plugged and unplugged". Problem is that it uses HAL and I know that HAL is deprecated. I found some working code, but it's working only with storage devices such as USB sticks, media players or CD-ROM drives. I want the whole thing: mice, keyboards, USB cameras, chargers; anything that is plugged in to the USB. How can I listen D-Bus events for any USB device plug and unplug? This is basically what I have now (also): import dbus import gobject from dbus.mainloop.glib import DBusGMainLoop def device_added_callback(device): print 'Device %s was added' % (device) def device_changed_callback(device): print 'Device %s was changed' % (device) #must be done before connecting to DBus DBusGMainLoop(set_as_default=True) bus = dbus.SystemBus() proxy = bus.get_object("org.freedesktop.UDisks", "/org/freedesktop/UDisks") iface = dbus.Interface(proxy, "org.freedesktop.UDisks.Device") devices = iface.get_dbus_method('EnumerateDevices')() print '%s' % (devices) #addes two signal listeners iface.connect_to_signal('DeviceAdded', device_added_callback) iface.connect_to_signal('DeviceChanged', device_changed_callback) #start the main loop mainloop = gobject.MainLoop() mainloop.run()

  • How to simulate a USB drive

    - by rursw1
    Hi all, Is it possible to simulate a USB drive with software only? I mean, for example, to expose a local memory space to the OS so the device manager will recognize it as a USB device. I'm not familiar with hardware implementation, but I'm sure that it is possible somehow to emulate the USB protocol. I began with this book - USB Design By Example. Can anyone please give me additional references to begin with? Thank in advance!

  • Lenovo W520 back usb port not working

EDIT 2: Booted up windows, and the port is working. I went into the device manager and looked at the USB settings. I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux. In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1 EDIT 3: Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled. Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.

  • How can I create bootable DOS usb stick?

    - by Grzenio
    I need to use this utility to change one of the parameters of my new WD hard drive: http://support.wdc.com/product/download.asp?groupid=609&sid=113&lang=en It has truly unreadable instructions: Extract wdidle3.exe onto a bootable medium (floppy, CD-RW, network drive, etc.). Boot the system with the hard drive to be updated to the medium where the update file was extracted to. Run the file by typing wdidle3.exe at the command prompt and press enter. I understand that this bootable medium should be some version of DOS? How can I make my USB stick a bootable medium compatible with this utility (I don't have a diskette drive)? I have Windows 7 and Debian Linux installed.

  • USB Hub powers down in sleep mode on Win 7 64

    - by Andy B
    This question has been asked before but not answered. I would like the USB hub to remain on in sleep so I can wake up the laptop from an external keyboard and mouse. I have set all the device drivers by unchecking allow this device to be powered down and disabled selective suspend in control panel but the hub still powers down. If I plug a keyboard or mouse directly in to the PC they remain powered and wake the computer its only when they are connected through the hub there is a problem. I have another PC running Win 7 32. If I set this up in exactly the same way the hub remains powered in sleep. Both PC's are Toshiba Satellites with multi-core celerons but one runs Win 7 32 the other Win 7 64. BIOS settings are the same. Any help would be appreciated even confirmation that this is a feature of Win 7 64.

  • Ubuntu live session crashes and boots to a black screen

    - by Bsc
    I heard about Ubuntu from a friend and wanted to test it out. I made a Pendrive Ubuntu 12.04 with a persistent file using Universal USB Installer. The first time I booted Ubuntu from the USB everything went like usual. I was just a bit exploring Ubuntu and had installed a few apps nothing more. Today after using Windows 7 for while again, I wanted to boot Ubuntu again. When I boot it, the usual loading screen comes up but after that it crashes and gave me a black screen. Is there a possibility to check the USB on errors or do I need to reinstall Ubuntu on the USB?

  • What causes "All-in-one USB Card Reader" to create 6 drives that always appear in Disk Management?

    - by tim11g
    I installed a "All-in-one USB Card Reader" to read SD cards and other media. It has caused six new drives to appear in Disk Management with six new drive letter assignments. These drives and letters are always present, even when there are no cards in the reader. When unused, they are labeled "No Media". Why does this multifunction reader cause these phantom Disks to appear and consume drive letters? Every USB port can (and does) allow removable media to be mounted and assigned a drive letter, and the drive letter assignment "disappears" when the USB drive is removed. Why are these card reader's drives and letters staying allocated permanently? Is there anything that can be done to make the slots work like a typical USB drive? (The reader is in fact connected to USB).

  • The cable of my USB port hub is too short - what to do?

    - by Anna
    Hi, I just bought a new USB port hub "MSY USB 2.0 4-port hub". It has two inputs: A small USB entrance input for external power (?) The problem is that the cable that comes with the hub (small USB on one end, large USB on the other - to input into my computer), is too short for my needs. Is there a solution to this? buying a longer cable might be risky, I know that it might cause problems with power. Is there anything else I can do to make it work? Thanks.

  • Parsing google site speed in analytics

    - by Kevin Burke
    I'm having a hard time making heads or tails of the Site Speed graphs in Google Analytics. Our site speed is fluctuating wildly from month to month, despite a large sample (the report is "based on 100,000's of visits) and a consistent web set up (static files served from an EC2 instance running nginx behind a load balancer). Here's our site speed, with each datapoint representing a week worth of data. Over this time period we modified our source and HTTP headers to increase our cache hits on static resources by 5x. Why would it fluctuate so much? Is there any way to get more reliable information from those graphs?
