I'm still looking for any suggestions. From a brief look at the source 
this message seems to be coming from a call to usb_bulk_msg.

Given that the dongles are OK in a via system does this likely suggest a 
compatibility issue with the USB host controller on the AMD 760G board?

I'm I likely to get anywhere trying to debug the code or will a USB 
analyser be required to work out what's going on?
