As a simple test, you could try taking the UHCI driver from 2.6.6 and putting it into 2.6.7. The files you need are drivers/usb/host/uhci*.* Doing this will probably rule out the driver as the source of your problem -- I expect the problem will remain even with the old driver in the newer kernel. If not, then we'll know where to look more closely. I wouldn't be surprised if this problem is related to interrupt handling, but who knows?
