This appears to actually be a USB hub of sorts:

and is a "legacy" product... meaning ATEN probably no longer support it.

However, in addition to the information requested by Kristian, can you
also please check these:

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

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

Does it recognize it via the US401 if the Windows computer is physically
disconnected from the US401?
