I am using Ubuntu 12.04 as a desktop operating system on my physical machine. When I start my computer i get an error

"An error occurred while mounting /proc/bus/usb."
Press S to skip mounting or M for manual recovery

when I press S i get my desktop and every thing works well

Any idea on how to fix this issue?

Thanks in advance

Ali

Boot in text mode and provide more info.

Also post output of

#sudo lsusb -v

#dmesg |grep usb

I have attached the out put of #sudo lsusb -v and #dmesg |grep usb

since I am new to Ubuntu I have no idea on how to boot it in text mode

Thanks,
Ali

Paste the following command's output:

cat /etc/fstab

Seems there is a invalid entry on the file.

Here you go


# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda1 during installation

# swap was on /dev/sda5 during installation

none /proc/bus/usb usbfs listgid=1002,listmode=0664,busgid=1002,busmode=0775,devgid=1002,devmode=0664 0 0

Okay, that clears it. You can comment out the following entry from your fstab like following:

#none /proc/bus/usb usbfs listgid=1002,listmode=0664,busgid=1002,busmode=0775,devgid=1002,devmode=0664 0 0

Once done, perform a reboot and the issue should not appear.

Let me know once done

Thanks a lot, I uncommented "none /proc/bus/usb usbfs" and everything is back to normal again

Cheers

Great to know. You can mark this thread as solved now
