I would. If we don't need to re-parse the report descriptor (because we
have an exact match), it means that we can keep the NUT-to-HID table we
created before. This also means that we don't have to DELINFO/DELCMD
each variable and command, before setting the new information (which
we'll have to do anyway) with SETINFO/SETCMD. That cuts the amount of
traffic between driver and server in half. It also means that no memory
(de)allocation will be needed, which is a plus too, since it can't go wrong.

Best regards, Arjen
