Why is the “Power + [U]” method not mentioned here? Is the result different? One of the mailing list messages suggests it might have been recently added, but I do see on my shipped NanoNote, in /proc/bus/usb/devices after “Power + [U]”:

T:  Bus=01 Lev=01 Prnt=01 Port=02 Cnt=02 Dev#= 85 Spd=480 MxCh= 0

P:  Vendor=601a ProdID=4740 Rev= 1.00
