From: Riwen Lu <luriwen@xxxxxxxxxx>
The format '%*ph' prints up to 64 bytes long as a hex string with ' '
separator. Usually the size of report descriptor is larger than 64
bytes, so consider using print_hex_dump_debug to print out all of it for
better debugging.

v1->v2:
- Add a prefix for the hex dump.
