Talk:USB BOOT mode

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

Picture rubber button

A picture of the carbonized rubber button would be nice. Some people might not recognize it as a shorting tool or overlook it because it's so small. With a picture they would know what to look for. I don't have a good camera myself.

Alternative shorting methods

What can people try to short the USB boot pins if they loose the carbonized rubber button? Or can they easily get a new one?
