Hi,

after more testing, I found out that only the first 3 control URBs complete 
successfully. I tried to duplicate the first GET_DESCRIPTOR(CONFIG) request, 
and the second one which worked before now fails. If I unplug/replug the 
device, the first GET_DESCRIPTOR(DEVICE) request sent to device 0 from 
hub_port_init fails:

c0450260 133702068 S Ci:000:00 s 80 06 0100 0000 0040 64 <
c0450260 134700018 C Ci:000:00 -104 0

Hope this helps to diagnose the problem,
