For certain (HP) printers the printer device_id does not only contain a static part identifying the printer, but it also contains a dynamic part giving printer status, ink level, etc. To get to this info various userspace utilities need to be able to make a printer class 'get_device_id' request without first claiming the interface (as that is in use for the actual printer driver). Since the printer class 'get_device_id' request does not change interface settings in anyway, allowing this without claiming the interface should not cause any issues.
