Anyone using a StarTech PCI420USB card? (USB 2.0, 4-port, PCI card)

[Rick Thomas <rbthomas@pobox.com>]

I just bought and installed a StarTech PCI420USB card for use in my  
PowerMac G4 AGP Graphics running Debian Lenny.

It's a PCI card that has 4 external USB 2.0 ports and one internal port.

When I try to plug a hub or a USB flash stick into it, I get the  
following messages in syslog:

The StarTech sales page says it works with Linux (and MacOS, and  
Windows, for what that's worth) but that probably means RedHat and  
x86, not Debian and PowerPC.

Anybody got any clues?

Thanks!
