If you haven't already, I'd start by generating large log files of the
scales interacting with the vendor-provided software. It's easy to do this
on Linux using https://www.kernel.org/doc/Documentation/usb/usbmon.txt.
Also, you have a USB HID device, which is a shortpath used by many vendors

If you have the source to the .NET library, you ought to be able to figure
out out the supported requests. Have you emailed them for more / better
documentation?

Do you have LibUSB installed? You'll need a binary backend in addition to
the Python bindings.
You can follow the installation instructions located at
http://sourceforge.net/apps/trac/libusb-win32/wiki.

Safoura,
Is your application code available in a git or SVN repository? Your
numerous cries for help have not provided much information as to the
structure of your Python + Java conglomerate software.

ivial development on the embedded side to make
this happen. At that point, you might as well pick up a Teensy or one of
the new XMEGA-with-USB chips and build your application from scratch.

Out of the box, the Uno should enumerate as a USB-serial / CDC device.
You'll need to make sure the kernel doesn't have control over the device
before trying to talk to it.
Call device.detach_kernel_driver() before device.set_configuration().
Also, I might recommend pySerial over pyUSB for talkin
Hi Safoura,
Perhaps we should take this off list, but I have a few ideas.
First off, you shouldn't need to touch WeDo_plugin - WeDoMore is the
self-contained library.
As for the distance - the WeDo is a rather tremendously shoddy piece of
electronics. Distance might not work if you've recently u

Have you monitored a USB transfer with the scale using its original driver?
I suggest the 'usbmon' kernel module. Use Wine or a VM if it's a
windows-only app.

Glad to hear it helped. Best of luck!

I wrote a python library to do exactly this. See
https://github.com/itdaniher/WeDoMore for details.
Additionally, it integrates with TurtleArt, the opensource project by PICO &
Walter Bender.

If you're running on Windows 7, you probably need to create a .ini with
libusb and may need to run your app as administrator.
