• HP Deskjet 720C USB printer doesn't finish

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the last page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. EDIT: It seems like the problem is with the last page. So if I am printing 3 pages, the first two work well but the last few lines in the last page are not printed. Any ideas?

• Chainload boot of Ubuntu installed on 32GB SD card from legacy Grub boot on USB

  - by Gary Darsey

  I have Ubuntu installed on a 32 GB SD card (in the Storage Expansion slot on an Acer Aspire One) with Grub2 installed in the same partition. I boot into legacy Grub on a USB drive and would like to boot by chainloading Grub2 from Grub (kernel/initrd or symlink booting would also be fine), but I haven't figured out how to do this from legacy Grub CLI. Output from blkid for this partition is /dev/mmcblk0p1: LABEL="Ubuntu" UUID="7ceb9fa7-238c-4c5d-bb8e-2c655652ddec" TYPE='ext4" / fdisk -lu information Boot indicator ID 83. Related entries in grub.cfg: search --no-floppy --fs-uuid --set-root 7ceb9fa7-238c-4c5d-bb8e-2c655652ddec linux /boot/vmlinuz-3.5.0-17-generic root=UUID=7ceb9fa7-238c-4c5d-bb8e-2c655652ddec... initrd /boot/initrd.img-3.5.0-17-generic I can't seem to replicate this in legacy Grub. Is there any way get Grub2 to chainload? How do I set root with UUID in legacy Grub? I prefer to boot from USB. Would Grub2 on USB (copying the grub.cfg generated during installation) be an option?

• Cannot boot from USB disk with "not a COM32R image" error

  - by Siva Prasad Varma

  After installing 11.10 on my Dell Studo 15 (Model 1557) laptop, it started to overheat. Recently it even shutdown twice saying that critical temperature has reached even when I was just idling (not even a single program was open except for Firefox). After learning that it is a problem with 3.0.0 kernel I decided to roll back to 10.04 LTS. I have downloaded the most recent 10.04 iso from ubuntu.com and created a live USB using startup disk creator in 11.10. But when I am trying to boot from USB I am getting the following error vesamenu.c32: not a COM32R image I have installed ubuntu from usb stick a couple of dozen times before this and I think it is not a problem with my hardware. Please tell me what to do.

  - by PatrickV

  I am using Ubuntu 12.04 and have multiple family members working on it with there own home folder. I have an USB disk and want to use it to backup my home folders.

I want to create one folder per home on the usb disk to backup the data to. But when I format the disk in EXT4 or FAT for example it is Read Only. How can I format the disk so it is accessible to every user. Best Regards, Patrick

• USB Bose speakers with ubuntu 12.04

  - by Richard

  On a fresh install of ubuntu 12.04 my Bose USB weren't working at all. I read through a large number of posts here and elsewehre on Bose or USB speakers. I tried many things (modifying a number of different files, etc.). This worked... sort of: USB Audio on 0 volume on startup The AlsaMixer works after I turn up the volume, but the sound crackles a lot. Also, having to use a term mixer to change sound isn't ideal. Any other ideas? Thank you, Richard

My dongle is of ZTE. I don't get what is going wrong.

• Lubuntu from USB

  - by WGCman

  I have An Acer Aspire 1362 Laptop with AMD Sompron 2800+ processor and only 256MB RAM, with Windows XP installed. I have downloaded Lubuntu-12.04-alternate-i386.iso and installed it to a 16GB USB stick. I do not want to install Lubuntu on my hard drive (yet!). I have got the USB stick to boot, and am working my way through the menu. At one stage, the installer wants to partition my hard drive, so I abort the installation. There doesn't seem to be an option on the menu to boot and run Lubuntu from the USB stick without putting stuff on the hard drive. How can I achieve this, please?

• USB Mouse/Keyboard not working

  - by crstn

  I installed Ubuntu 11.10 after booting it from a USB drive. Everything worked fine there, after booting the keyboard worked in grub but not after Ubuntu was booted. I can unplug either of them and plug them in via a PS2/USB adapter and the device will work. After switching a couple of times, I got the keyboard and mouse both working via usb but after I rebooted either stopped working. How can I fix this? The mouse is a Razer Krait and the keyboard is a Logitech ClassicKeyboard 200.

• Why is using an external USB drive or USB printer causing my system to hang?

  - by thepd

  I am having some troubles using various external hard drives and my printer, all of which I connect using USB. The majority of the time, when I connect either of these devices, my system freezes up completely after about 10 minutes. They work just fine prior to that moment. I've also not noticed any problems using a USB mouse. I'm running Ubuntu 10.10 and have tried using a newer kernel (a 2.6.36 Maverick kernel from the kernel ppa, as opposed to the default 2.6.35 one) to no avail. I'm using a Dell Studio XPS 16 (M1647) which is a sort of newish laptop and so my guess is this is probably some kind of driver bug. Is there anyway to debug these sorts of issues? I've looked through some of my logs (/var/log/messages seemed the most useful) but haven't been able to find any kind of USB related logging nor anything interesting happening prior to the hang.

• Trying to boot from USB on Asus q200e-bhi3t45 just brings me to grub menu

  - by Krash Kharma

  It's been a struggle every time I've tried to change my OS on this machine. I honestly don't even know how it works whenever it does. I've somehow managed to get Windows 7, Windows 8, Mint 14, Ubuntu 12.04, and 12.10 to work at random times but it's always after struggling with it and googling for random chance fixes and suddenly something clicks and it loads from usb, but 99% of the time, every time I try to boot from USB to install a distro (in this case, I'm trying to get ubuntu-12.04.2-desktop-amd64.iso to work) my pc just comes up with a grub menu ("Minimal bash-like blahblahblah - grub ") I don't know why it works when it works. Right now I've tried everything from with/without Fast Boot in BIOS, with/without CSM, with/without secure boot, to changing BOOTx64.EFI to bootx64.efi to downloading a new bootx64.efi to copying it to every folder on the usb.... It makes no sense to me. Sorry if this has been asked before but I can't find anything

• usb drive filesystem?

  - by purbleguy

  So, school is approaching quickly, and one of the things on my supply list is a usb drive. Now I'm asking myself what filesystem to use. After some research, I found ext4 to be the most stable drive filesystem. But, I also found that Windows (The OS used by every computer in my school) can't read ext4 formatted drives without special drivers, and I'm sure the school wouldn't be too happy with me having to install the windows ext4 drivers on every computer I use with my usb. So, my question is, Should I use fat32, one of the ext filesystems (2, 3 or 4 would work) or NTFS, I have an ubuntu laptop, a Mac desktop, and of course the school computers I use are Windows, so which would be the best filesystem for my usb.

• How to install Ubuntu using a USB stick?

  - by J. N.

  I cannot install Ubuntu 11.10 from a USB stick. It doesn't boot to Ubuntu page for installation but remains on Windows 7. I've downloaded the 11.10 version iso file and burnt it to a USB stick. After I inserted it, the USB stick is a symbol of Ubuntu installation and I clicked wubi to try to install it. But it didn't boot to Ubuntu but stayed on Win 7 after restart. It occurred error and said "windowsBackend" object has no attribut "cd_path" when I chose "Help me to boot from CD". I thought it's the problem of my computer model (acer travelmate 8481), but it can't boot on an old computer using XP as well. How can I solve this problem and install Ubuntu to replace Windows?

• USB key will only be mounted by gparted [?]

  - by user2413

  Hi, When I insert by usb key nothing happens (i.e. the drive is not visible). I can mount the USB drive from gparted though (and then it's suddenly recognized). It's not particular to any USB key. This only happens on my laptop (on the desktop the same key will be mounted upon plugging it in without any problems). Finally, the key is formated as fat32 and dosfstools and mtools are installed (through gparted claims otherwise). what's the catch? EDIT Also, gparted offers me the option to mount the key on "/" : shouldn't that be "/media" (or has this changed ?)

• unable to boot from live USB!

  - by ramblinman

  Linux noob here. I was messing around with my new dual-boot (win7 and the latest ubuntu, 12.04 I think?) Long story short, I deleted some partitions that I shouldn't have. When I boot up the machine, I get: error: no such partition. grub rescue _ I know that I could probably fix this by booting from the live USB. But I can't boot from the live USB either! On startup, I can get "boot from drive" options by pressing F12. (This is how I installed Ubuntu in the first place.) But when I select the USB drive, I get this error: error: no such device: [long string of letters and numbers]. grub rescue _ I've searched around for a fix but most threads addressing the first problem suggest booting from live drive. And I can't do that! Any help much appreciated.

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• Ubuntu 12.04 won't boot from USB

  - by user986871

  I downloaded Ubuntu 12.04, then using the tool Startup Disk Creator i made the live usb. I checked that it's bootable Device Boot Start End Blocks Id System /dev/sdb1 * 62 15635593 7817766 c W95 FAT32 (LBA) Now on my lap top it boots nicely, but on two other machines that don't have any installation of ubuntu(no Grub) it doesn't boot. I changed the booting order so that USB is before HDD. So i think i did everything i know, but no luck. How can i use this USB drive on other devices that don't have any previous ubuntu installation.

• What to do about USB support?

  - by RhZ

  USB speeds are consistently slow in ubuntu, and have been for years. I just bought two new machines with usb 3.0, running 10.04, and yet nothing has changed, top speeds are only about 8.0 MB per second and they quickly drop to 2 or less. Its very frustrating. Are there any fixes for this at all? I find almost nothing online. The board is a gigabyte 970A-DS3 motherboard. Is there any driver I should install? I am using brand new usb sticks (kingston) and making sure to plug into the 3.0 (blue) slot.
