Error on startup - Ubuntu Desktop 12.04


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

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

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
