I'm a real newbie to linux. Anyway the problem is that my USB doesn't get recognized anymore which is really annoying because I need information from it. I've read like a zillion threads how to manually mount it but I really can't it to work. I hope it's just some easy, stupid problem where any of you could help me out quickly..

Here is the syslog:

kernel: [ 6872.420125] usb 2-2: new high-speed USB device number 11 using ehci_hcd

Thanks in advance

Looks like your system does not recongize the parition. Are you sure the device even works and have you formated it in a way that Linux will support? –  Ramhound Jun 1 '12 at 17:59

Well, from the log it could be that the partition table of the USB device is messed up.

apt-get install -y testdisk
testdisk /dev/sdc

and try following the on-screen pointers for scanning and recreating the partition table.

This might help if the problem is not as severe as being hardware related already.
