On mandrake 9 with the 2.4.20-rc1 kernel  "/dev/usb/ttyUSB0" is a link 
to /dev/ttyUSB0.

This is the device I use so the device should be OK. The major/minor 
numbers for /dev/ttyUSB0 and /dev/usb/ttyUSB0 should be the same.

I use /dev/ttyUSB0 for everything I ever do with the device.

You should definitely turn on the full usb serial debugging to get some 
more info from the driver methinks.
