Hi,

There is a slight difference between the bcmxcp_usb driver and this
ups.
If you look at the descriptor it tell you that the protocol is reported on
the interface level. The interface level say HID device.
If you look at the bcmxcp_usb driver it say vendor protocol on
the interface level.

So this should follow the usb hid device rules on the interface.

Regards
Kjell

isn't bcmxcp_usb built on the same idea?
iirc, they were just encaps'ing the serial protocol over usb (not sure
about hid). Another example of "strange hid approach" is energizerups,
but it's hiddev only. Anyway, all this might give you some ideas ;-)
