'[EE] Communication protocol used by UTD2102C oscil'

Hi,

I've just bought the UTD2102C digital oscilloscope (
http://www.uni-trend.com/UT2102C.html ), but unfortunately the
accompanying software doesn't work with 64-bit Windows 7, neither with
Linux.

I've connected it to my wife's 32-bit machine and recorded the USB
transmitted data, when working with 32-bit Windows. Generally the
protocol seems to be relatively simple (I could distinguish the
control commands transmitted via control transfers and measured data
transmitted vie bulk transfers), so it should be possible to write an
application working with UTD2102C based on libusb.

Anyway it would be much easier having the description of the protocol.
Maybe this protocol is similar to better documented protocols used by
scopes of other brands?
I've asked the manufacturer about availability of the protocol
description, but I do not expect too much (form my previous experience
in similar problems).
I'd appreciate any pointers and suggestions.
-- Best regards,
WZa

There is a software based USB analyzer tool that you can use. I do not
remember the name. This should give you some good information on the
protocol.

A blog that discusses the reverse engineering the USB of a different scope
from the same manufacturer.
