Relative.
XSetDeviceMode can generate a BadDevice or BadMode error.

may also occur if some other client has caused
the specified device to become the X keyboard or
X pointer device via the XChangeKeyboardDevice
or XChangePointerDevice requests.
BadMatch This error may occur if an XSetDeviceMode
request is made specifying a device that has no
valuators and reports no axes of motion.

also be returned if the specified device is not
capable of supporting the XSetDeviceMode
request.
