You are probably already aware of this, but the erata posted on AMD's web site (http://www.amd.com/us-en/Processors/TechnicalResources/ 0,,30_182_739_9004,00.html) for the AMD-8111 chip claims that the USB 2.0 port doesn't work in high speed mode. If your testbed has this in it, you may need to use a PCI card.

No, I wasn't :/ Thanks for the info. So If I sum up: high speed USB is not working on the Mac because of a USB system software bug, and on PC because of host controllers bug. Maybe we should reconsider a Firewire connection instead of the USB.

You might want to open up your Macs and see who makes the chips... I have been told by third parties (actually users on daw-mac, not technical people!) that's the chipset in the G5s. I don't know if they are correct, because I don't have anything newer than a Quicksilver here, but it fits problems people have been having with them...

I don't have access to a G5 either. Not yet. I had a look at the G5 hardware specification. It mentions chips named U3H and K2 and a PCI USB controller connected to the K2 chip. Don't know if they are just code names for commercial chips. I thought that Apple was designing its own ASICs.
