XSetDeviceMode(3) can generate a BadDevice or BadMode error.

DIAGNOSTICS

BadDevice
An invalid device was specified. The specified device does not exist or has not been opened by this client with XOpenInputDevice(). This error might also occur if some other client has caused the specified device to become the X keyboard or X pointer device through the XChangeKeyboardDevice(3) or XChangePointerDevice(3) requests.
BadMatch
This error might occur if an XSetDeviceMode(3) request is made specifying a device that has no valuators and reports no axes of motion.
BadMode
An invalid mode was specified. This error will also be returned if the specified device is not capable of supporting the XSetDeviceMode(3) request.
