Hello,

First, sorry, this mail is quite long, because of logs.

I've downloaded these two scripts and ran them on the GTA04 with these
results :

GTA04 resume from suspend (Openmoko charger cable were plugged before
suspend) :

Next unplug/replug have same results than the last one (floating id). Is
it an issue of not re-initialized value for id ?
Do you need more trace ?
