Linksys WPS54GU2 Printserver USB Problem

I can't get the WPS54GU2 to print to my Lexmark X125, which has a USB
connection.

The parallel port on the print server works fine to my Laserjet 1100.

The USB printer works okay when connected directly to the computer.
The I set it up with the Print Server Utility and connected it to the
print server.

I cannot get the print server to print on the Lexmark. More revealing
is that I cannot print a test page directly from the web-based
utility. When I go to the Printer Status page (under Status), there
are two :Print Test Page" buttons. The test page on the parallel port
works. The test page on the USB port produces nothing.
