Some devices (E.g. specifically this one) expect their interrupt endpoints to always be serviced. In this case, the device has an on-board watchdog and will reboot (disconnect and reconnecting to the USB) if it is not serviced in a timely fashion. > > + case 0xC0: /* down */ > > + dev->x = (pkt[1] & 0x7f) | ((pkt[2] & 0x07) << 7); > > + dev->y = (pkt[3] & 0x7f) | ((pkt[4] & 0x07) << 7); > > + dev->touch = 1; > > + dev->press = 1; > Since the device does not report real pressure readings don't try to > fake it, reporting touch is enough. I believe that this is because some userland libraries, particularly tslib, require the pressure reading in order to believe the device is functioning usefully. Specifically, consider plugins/input-raw of tslib's source package which uses pressure rather than touch.
