I had precisely the same problem with USB-2 flash (both old USB-1.1 
flash and digital camera - Kodak C340, uses ugen) work perfectly all 
right. MB: Asus A8N (nForce4 based). The problem went away with 
retrying to get device descriptor in usbd_new_device (see patch below).
I've submitted PR (usb/103167) but so far there's been no reaction at all 
:-(

Hope this helps,
Vladimir
