I have been searching for information on how to obtain status
information from the Logitech wireless keyboards and mice.
For ordinary keyboards it is well known how to query the keyboards for
the LED status. For the Logitech keyboards I would suspect that the
method of obtaining battery level and RF channel information would be
similiar - write some magical values on to port 70 and read back the
response on poort 71, only I don't have a clue what those magical values
Does anyone here know the answer to this ?
