No, USB suspend is supposed to be orthogonal to configuration. That is, suspending it then resuming it doesn't change configs; see the ch9 state transitions diagram. I can imagine device-specific bugs, which their drivers would need to cope with. And sometimes features ... example, re-enabling local controls so suspend of a remote host (in a control room, say) can't lock a machine in a dangerous mode. - Dave ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
