I have a SanDisk 16GB USB drive that is not being detected by Ubuntu 14.04 but is detected by Windows 7.
lsusb detects it but sudo fdisk -l or blkid doesn't.
Even GParted and Disks don't detect it.
Here's some terminal output:

I don't know what to do anymore to get it detected and I don't want to format it as it contains important data.
I backed up my data in another laptop, formatted the drive in Windows 7 but still it's not recognized. The funny thing is that Windows 7 detects it and uses it fine but it's not detected in Ubuntu except by the lsusb command. Weird.

EDIT 2
Something interesting:
The USB DOES NOT work in guest mode but WORKS in live session mode. All running Ubuntu 14.04.
Re-installing is not an option.
EDIT 3
Other USB's don't work, this is a problem with the system not the USB.
