Thanks for applying it. It would be great if you could take this on,
since you have the hardware. I described how the vendor software
reads the sensors on these boards in my reply to v1 [1]. Two more
details:

- The vendor software reads up to 10 input reports and only checks
  that byte 2 is 0x01. On 0db0:0076, the response echoes bytes 0-1
  (FA A0) and 9-10 (01 FC), but I could not confirm that for these
  controllers.
- Besides the bootloader command, output report 0x01 with byte 1 set
  to 0xD0 resets the controller, and feature report 0x52 with byte
  184 set to 1 writes the RGB settings to flash.

If any change touches the 0db0:0076 path, I can retest it on the
MS-7E61.

Thanks,
Tomasz
