I am not too familiar with game controllers, but I think this would
mean 4 bytes (24 bits / 8 bits-per-byte).
The support for arrays of buttons in libhid is not that great, either.
If you are using Linux (which the output tends to imply), then you
might be interested in the kernel input API.
Yes I am using ubuntu 9.04 and I have written a driver using the kernal
input API for the switch part. The problem is that also on my Saitek Radio
Panel is 20 7 segment led displays that the input API does not support and I
have them working using libhid. I guess I will have to try to get hiddev to
work but when I use it it does not give me back the correct vendor of
product ID. Thanks for your time.
