It appears you have no partition table and an ext2 fs occupying
the whole device. This should be OK.
Try 'mount -a /srv/usb /dev' and see if /dev/sdUx.y appears.
If yes, try 'ext2srv -f /dev/sdUx.y/data && mount /srv/ext2 /n/linux'
If no, try 'cat /dev/usb/ep4.0/ctl' and see if you get something like:
enabled control rw speed high maxpkt 64 pollival 0 samplesz 0 hz 0 hub
5 port 6 busy
storage csp 0x500608 vid 0x058f did 0x6387 Generic 'Mass Storage' ehci
where "storage" means it's been recognised as a mass storage device,
and "busy" means it's already being handled by the usb/disk driver.
