It sounds more and more like a USB 2.0 thing.
Last night I installed VPC 7 on my new G4 laptop (with USB 2.0). I installed Win98 SE and no dice. The device is recognized as an 'unknown' USB device, and re-installing hardware/drivers etc. could not get it to work.
But, it works great on my old G4 laptop with USB 1.1.
So, I fear USB 2.0 mac users are out of luck.
There's one more thing I want to try: I have a USB 1.1 PCMCIA card which will fit into the 15 and 17" powerbooks. I'm going to install it and see if it might work.
