Auch.. It seems as if every read hangs. What happens if you use another
USB Host module? You seem to be using 'usb-uhci'. Try 'uhci' instead,
and see if it works. On my box, 'usb-uhci' works better than 'uhci', but
perhaps on yours it's the other way around.

In what state are they? You can see that with 'ps ax':

  PID TTY STAT TIME COMMAND
 5962 pts/0 S 0:01 slrn
               |
 Sleeping? ----/
 
 5985 pts/2 R 0:00 ps a
               |
 Running ------/

If it's in state 'D', you're going to have to reboot, or simply wait for
them to time out (might take long). They're hanging in a kernel call, so
any signal you send them will be received when the kernel call returns,
which might take a long time (the forementioned timeout).

Good thinking, but if you can't even do 'fstab -l', you sure can't mount
it, no matter the filesystem.
