If you're screwing around with inf files, (in my opinion) you're doing it wrong.

I (finally) got windows XPand ubuntu working with (almost) the same code, and 
no 
inf files.

http://github.com/karlp/karlnet/tree/usbmaster/producers/pyhid/ has the simple 
code, and the README there is....

--- copied

You'll need pyusb 1.x from: http://pyusb.wiki.sourceforge.net/
I used pyusb-1.0.0-a0, and just ran the regular python setup.py install.

I did that before I had libusb-1.0 installed.

Steps for getting libusb-1.0 on windows.... (at least, what worked for me)

1. from http://www.libusb.org/wiki/windows_backend
    That's from libusb itself.  NOT from libusb-win32.
2. get the latest package, I used 2010.05.17(pbr277)
3. for me, on winxp (32bit) I copied libusb-1.0.dll and libusb-1.0.lib from
    the MS32\dll directory, over to \windows\system32


Verified working on ubuntu 9.10 (with libusb-1.0-0) as well as windows xp

Cheers,
Karl P
