Hi Pete, Randy,
I have an awk program that I use to run through Kitty USB Analyzer html
pages and decode setup data packets for device, configuration, endpoint etc.
generic descriptors, into USB spec type formats. It is table driven and
could be extended to some of the more difficult descriptors, such as HID or
audio etc., but would take an expert in those descriptors.
In any case, if you give me a URL to a few usbmon text dumps, I will try to
do a converter to run usbmon output through this AWK decoder program. (I
don't have a working Linux system right now). If I can do a converter I
think this GAWK program will help make the usbmon stuff more helpful.
Regards ~Steve
