I'm trying to get a handle on the sleep timeout of the USB port to which I've connected an external USB-powered HD. With 'Power Options > ... Advanced Power Settings > ...USB selective suspend setting' set to Enabled, the external drive does power down to sleep mode, but, as best I can determine, with a timeout of ~10 minutes, irrespective of the general power settings (e.g., internal HD power down:Never, sleep: Never). But I can't find what actually sets the timeout of the USB port. (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Diagnostics\Performance\Suspend gives lots of USB timings, but these are in ms, nowhere near the minutes I observe.)
Does anyone know what controls the USB port timeouts and how to vary or at least verify them?
