All of the previous answers talk about a USB suspend mechanism, i.e. a "logical power-off", they will never physically cut the VBUS +5V from the USB port. Only a few hubs can actually cut VBUS as described here. The hubpower tool can do it (if the hub supports it).

At present VirtualBox 4.3. does not support USB 3.0. As a workaround you may succed in connecting your device to a USB 2.0 port or a USB 2.0 hub. According to VirtualBox ticket #8873 we may try to attach a USB 3.0 hard drive as a raw disk to the guest OS for a faster transfer speed but this may only work in some cases.

When you ran mount only sda5 (your /) was mounted, and it was read-write (rw) so you should be able to write to it. Normally, most of the directories like /sys, /bin are only writeable by root (you'd need sudo first), but your home folder should be writeable to your regular user. Can you create any files in your home folder? Maybe your gui file manager is ...

I know this question is from 2012 but if someone is having trouble: Try to reset the bios by removing the CMOS battery and see if that works. It could also be defective RAM. I've had that if I had bad RAM the computer wouldn’t get past the bios loading screen.

Sorry you cannot launce wubi.exe from bios, it is a Windows program. Install it in Windows. "Burn" your Ubuntu iso file to your usb stick, and from wubi install it (inside windows) You end up with a windows boot, and can run Ubuntu in wubi, this is not a dualboot.

You can not just add casper-rw to a Live, (non persistent), install of Ubuntu and expect persistence. You can make this method work if you press F6 at boot and add " persistent", (That is -space-persistent), to the menu after "quiet splash --". You need to do this every boot. Or You can make a Persistent install using Startup Disk Creator or UNetbootin ...

About an hour ago, I had the same problem. I changed my UID, logged out and logged in. I stuck an external drive in the USB port and saw that it was mounted. When I clicked on the drive icon on the Desktop, UBUNTU said that it doesn't know how to open the file. You are lucky since the error message lead you directly to the problem.I am using XUBUNTU ...

I can barely follow your full question, so I'll just answer the "Input/Output error during install through USB", assuming it's a USB input/output error. If you could post the exact error messages (should be some in /var/log/syslog or dmesg, maybe even with lsblk to see which drive is which) that would help show if it's USB errors or HD errors. I get ...

a simple test: USB 2.0 is defined as a technologie which can transport data from a to b with a speed up to 60 Megabytes per second. (We are talking about Megabytes, not Megabits.) But You will seldom find an USB 2.0 device that needs this speed and never find an USB 2.0 pen drive that can reach this speed. So make the following test: Just take some big ...

Add the user as suggested by other answer using usermod command. Run the command id. You should see vboxusers in the list. If you don't see that, you may restart your computer and try id again. When you get vboxusers listed as a result of running id, you're good to use USB with virtual box.

I was able to configure the wireless device with iw and wpa_supplicant rather than iwconfig. I essentially followed the instructions here, which was based on this.

There is nothing wrong if files open in Ubuntu. Just copy your files to your computer. For copying you may use Nautilus (Ubuntu's file manager),or you may use twin-panel file managers like Total Commander in Windows if you prefer. (There are many of them in Software center such as Gnome Commander, Krusader,etc.) Of course you may use command line, as ...

I had a HDD fail on me a few months back and my advice is to clone the drive to back it up before you start with recovery tools, rather than just copying it. Copying will only copy files that are visible and indexed by the file system, whereas cloning will literally copy every sector of data on the drive, including lost/deleted files and 'junk'. I believe ...

So... I'm not too clear, you can boot from the usb successfuly, and you're now running Ubuntu live? Or you can not boot from the usb and can not run Ubuntu yet? If you couldn't get the usb to boot, you could try the the same program I used way back when I was using windows to create a bootable Ubuntu usb, very easy, about 2 or 3 clicks if I recall ...

As long as you don't install any proprietary drivers and are using 32 bit, your Ubuntu USB should boot almost any computer that is up to minimum spec, PAE, 512MB RAM, 700 MHz processor, etc. There are versions you can run if you are planning on using older computers, say without PAE, or enough RAM.

turn off the computer, then turn it back on and press F12 to bring up the boot menu. That should permit your computer to boot to alternate media such as an ubuntu live CD or USB. If it does not boot to that media, you should consider the possibility the media itself is bad or that the ubuntu boot image on that media is corrupt. To be clear, CHROME has ...

Yes, you should be able to retrieve the filesystem as long as you don't continue to write to it. The more stuff you write, the less chance you have of getting your filesystem back, because you'll start overwriting stuff. You can use the Testdisk software do do these things, but if you've never done it before, you might possibly want to make a backup of ...

I'm not sure that a hard drive can be unformatted, or the formatting process reversed. Generally formatting a disk is a path of no return. You may need to buy disk recovery software to try to recover what you can from you external HD. Back in 2011 I successfully used a product called R-Studio. Then, I used the Windows version and it worked for me. I just ...

Obviously some sort of error occurred. I've seen something similar a couple of times. Often what works best for me is to boot the computer to a live cd and use gparted from that cd to pretend to try to slightly resize any partition. It seems the action causes gparted to check and adjust its partitions so everything is corrected.

You mentioned that you had wired internet before, but when you got this wireless adapter, did you get a wireless router with it as well? If you know the name of your wireless network and the security key (if it applies), do you see an icon in the upper right that appears as a pie shape (that's the best way I can describe it)? That would be the wireless icon. ...

The amd64+mac version should work on both the Mac and the PC. The difference between the amd64 and the amd64+mac is that the amd64 version is 'multi-catalog', ie it can boot on either BIOS or UEFI systems whereas the amd64+mac version only support BIOS booting. The problem is that Macs are not able to boot 'multi-catalog' disks. However, you can get your ...

If I understand you correctly, what you want to do, is use your flash drive as the 'harddrive' in Virtualbox. This way all your changes will be reflected on the flash drive. In order to do this, you will need to make a virtual hard drive that points to the physical device, then use the virtual hard drive with Virtualbox. Use the following command, ...

"We are unable to get it to connect to any computer" sounds like the USB is pretty much dead. But does anything show up on linux/Ubuntu from lsblk or sudo blkid or sudo fdisk -l? If nothing about the usb, that's a big red flag that it's dead. What are the messages in dmesg or files in /var/log/ (like /var/log/syslog) when it's plugged in? Should have some ...

I'm not sure if this will work, but these are the files owned by vbosusers on my machine, where USB is working right under Virtual Box. sudo find / -group vboxusers /dev/vboxusb /dev/vboxusb/002 /dev/vboxusb/002/003 /dev/vboxusb/001 /dev/vboxusb/001/004 In another machine it looks like this sudo find / -group vboxusers /dev/vboxusb So it looks like ...

As a good alternative to badblocks you can try diskscan ( from terminal:apt-get install diskscan). It measures the latency time of reading sectors and it also reports bad sectors. The longer the latency time the greater the probabilify of an error developing.

Does the drive work normally on other computers or windows? Can you read & write to the entire drive? I've used external usb drive "cases" before, where you plug in a HD or cd/dvd drive, Ubuntu (Linux Mint) usually sees the HD's as /dev/sdc (for example) like a regular drive. No need for usbmount or pmount, but maybe yours is newer or weird somehow. Are ...

That's unusual. Did the card work on windows with the same card reader, and writing more than 32GB worked ok? Any changes with a different card reader, in Ubuntu or windows? There are lots of differing card readers of varying quality, some slower, some unreliable, some can't handle SDHC or SDXC (like this one) even though they may advertise they can.

Your hard-disk itself has a problem on one of its sectors and the hard-disk problem needs to be fixed before you try to re-use it. All that you've done until now is running file system repair tools which all assume they have a good hard drive to work with If you really suspect hard drive failure, (which is what this looks like) you should run badblocks In ...

This looks like a job for gparted - install it if not already done so, unmount the disk (either 1st or when it prompts you to), & see if you can extend it to 64g. If not, it may be a problem with your card reader?

Your PC has an Intel Atom processor and only 1GB of RAM, so Lubuntu was the right choice, but some of the Intel atom processors do not support PAE. So follow the official Ubuntu PAE instructions and if that fails, you basically do have a pretty expensive doorstop.

You can find instructions here: http://www.pendrivelinux.com/creating-an-ubuntu-live-usb-from-cd/ :) "Persistence" is what they call it when you can save your settings and data and it's not just live.

The error device descriptor read/all, error 2 indicates a unrecoverable problem in the communication with the device on the USB bus.

I once used dd to copy a live iso onto a usb drive (sd card specifically). It didn't use a regular MBR, apparently no MBR at all, just something like the cd-type ISO9660. What should have worked to fix it (that I didn't try at the time) would be to use something like gparted to: write a new MBR to the drive, then create new partition(s) and format them ...
