What happens when no devices are attached to the adb chain and the
kernel tries to init?  My experience is that it locks up after
printing "adb:  bus subsystem" (or whatever).
Unfortunately, I wasn't able to do comprehensive testing (trying
different combinations of devices attached and not attached) because
I'm trying to keep my machine online to keep my users somewhat happy.
If you want, I can do some better testing some morning.
I just plugged in the keyboard and mouse.
