If we have two devices with the same default ID, they may get assigned different IDs after re-probing. Any ideas how to cope with that? On my 3400, after a snooze, sometimes the adb bus has been reset and sometimes it hasn't. I haven't been able to discern any pattern, e.g. it doesn't seem to depend on how long the machine is asleep for. I believe that the power to the adb bus is supposed to stay on during sleep, so I don't see why it's getting reset. Paul. [[ This message was sent via the linuxppc-dev mailing list.
