He's still not provided info requested:

1. Check your bios settings and see if you have a setting for 'legacy
usb' or similar. The US401 is a USB 1.1 device, and if you are only set
to handle 2.0 it may not get recognized.

2. Check your System|Administration|Printing settings. Your printer
should be on a usb Device URI. Example; my Canon MP750 is on
canon:/dev/usb/lp0.

3. Does your system recognize the printer if it is directly connected to
your system without the US401?
