my USB driver is not working any more

[kritik]

Today one of my USB Sticks stopped to work. It could not be mounted any more. But I see it from lsusb.

and if I see fstab, I don't see my USB

What can I do to repair my USB-stick?

I would try to create the partition again plus format it with GParted. If that doesn't do it then it might be toast (they do go bad, more often than people want to think).
