nope. you collect them. then you learn what they mean. wash, rinse, repeat.

well, i ran the log you have thru spike4.pl, and its pretty much all 1
or 2 byte reads/writes, other than the fw upload and an obvious indent
query in Urb 28. you may never be able to find out the purpose of all
those commands, but they can possibly be left out, or if not, you just
repeat them.

get a series of windows traces of small (resolution and scan area)
color/gray/binary scans. post the raw ones where folks can see them.
then clean them up with your choice of tools from the
experimental/usbsnoop dir.

take the attached libusb prog and use it to simulate one of those
traces. keep your hand on the power cord :) and see if you can get
blocks of data out of it.
