While working on the driver for the device: ID 0681:0002 Siemens Information and Communication Products Gigaset 3075 Passive ISDN I have repeatedly encountered an error state I can only clear by disconnecting and reconnecting the USB cable. The device just stops responding to commands. (Specifically, the USB OUT transfer sending the command to the device is successful but the expected reply from the device is never signalled.) This state persists even if I unload the driver and load it again: the driver probes the device just fine, switches the altsetting successfully, but none of the initialization commands get any response. When I unplug and replug the USB cable, however, the device immediately starts responding normally again. I should mention that this device is self-powered, so unplugging the USB cable does not power down the device. In fact, its main function (ISDN PABX and DECT base) is unaffected by the error or by the unplugging. I'd like to spare the users of the driver the hassle of pulling the plug. So what does disconnecting the USB cable do that even unbinding the driver doesn't? What can I do programmatically from within the driver to get as near to an actual physical disconnect as possible?
