People who have just installed 2.6.30 generally don't feel like reverting to 2.6.29. :-) > Under X the device > file is always open. Possibly 0 should be ignored as a timeout for HID. People don't always run under X. But even in VT mode, the device file is open while gpm runs. Nevertheless, my point was that such a large percentage of mice do poorly at remote wakeup, we should avoid autosuspending mice entirely -- unless remote wakeup doesn't matter, i.e., when the device file is closed. That means don't autosuspend regardless of the timeout value. Also, usbhid can afford to be selective. Even though mice behave badly, we can continue to autosuspend other sorts of devices.
