Hello,

I have a usb flash drive.

[ When plugged into my linux, /var/log/messages gives:

Jan 11 10:28:14 redstar kernel: [  388.588091] usb 1-3: new high speed

]

It has an ext2 filesystem on itself and can be, in linux, mounted:
mount /dev/sdb mnt
without errors, and works.

What should I do to be able to work with the drive (read/write) in plan9?
(When I plug it into my plan9 machine, I don't see any entry like
/dev/sdUXX, I see 3 entries under /dev/usb/, ep4.0, ep4.1 and ep4.2,
which appear/disappear as I plug/unplug the device. Running usb/disk
claims sth. like 'there is no disk unhandled').

Thank you for suggestions!
Ruda
