Sending USB commands with Python

[Jorge Mazzonelli]

Hi,
I recommend the use of the module PyUSB in sourceforge:
http://pyusb.sourceforge.net/

Also take a look to the tutorial :
http://pyusb.sourceforge.net/docs/1.0/tutorial.html

as far as I can remember, you'll need to first find the device based on the
idvendor / idproduct (provided in the pdf). then you'll need to setup the
configuration (usually the default but on your case you'll need to check
which one, since the doc says there are 2 exposed). then the endpoints.
(all of this is on the tutorial)

With that you need to write the command and then read the result from the
endpoints.
The status command you want will be 0x1B 0x41.

Hope this helps.

Jorge
