NOTE
In the future, the maximum report size may be increased, to
support transfers of larger packets. Alternatively, additional
reports may be added with larger maximum sizes.
The actual data sent in all of the reports looks like:
0 Report ID
1 Packet Length LSB
2 Packet Length MSB
3 Packet[0]
4 Packet[1]
5 Packet[2]
...
N+3-1 Packet[N-1]
This data includes the Report ID, which is required if more than one report is defined in
the HID report descriptor. The actual data sent and received has a maximum length of 35
bytes. The Packet Length header is written in little-endian format, and it is set to the size
(in bytes) of the packet sent in the report. This size does not include the Report ID or the
Packet Length header itself. During a data phase, a packet size of 0 indicates a data phase
abort request from the receiver.
