Actually I'm not so sure. I generally describe USB_SUSPEND as relating to whether or not the USB "suspend" state is used -- selective suspend and resume support. Calling driver suspend() and resume() methods is orthogonal to that ... except that to use the USB "suspend" state, any drivers should have been properly suspended. Now, it's also true there's something fishy going on since this works with USB_SUSPEND but not otherwise. What exactly that might be, I'm not sure given the info I've seen so far. - Dave ------------------------------------------------------- This SF.Net email is sponsored by Yahoo. Introducing Yahoo!
