Hi, pardon me for jumping in, but by chance I read this mail and maybe could shed some light over this topic.
In my box there is a KT266A based board. I also tested the usb and the usb-uhci drivers, but first had no luck with both of them (transmitting files from a digital camera). I long had communiction breakdowns when using gphoto2 (which itself uses libusb) when trying to download pictures out of my cam. I'm using ACPI to get some powersaving on my box, according to http://cip.uni-trier.de/nofftz/linux/Athlon-Powersaving-HOWTO.html, but had to deactivate the powersaving to stop the breakdowns. Just a few days ago I fiddled around in the BIOS and activated both PCI Delayed Transaction and PCI Master Read Caching, and now I do not have any breakdowns anymore, at least with usb-uhci (but active powersaving). Maybe you have to look into your BIOS settings ...
