pyusb and libusb-32 problems

[metalayer]

Hi there, hope this is the right section to ask this.

I am trying to use libusb-32 and pyusb (with python 2.7) to control a usb device on my windows 7 machine, as demonstrated here - http://www.ladyada.net/learn/diykinect/. The libusb-32 filter driver on my device has installed with no problems (test util gives the proper endpoint data) but I am getting a "No backend available" error when I run my python code.

Can anyone with experience of these tools give me some advice? I am thinking there is some sort of version conflict between pyusb and libusb-32, does anyone know which version of both tools are compatible and if the python and windows version is an issue? I have already looked through a lot of the pysub mailing list archives and asked on there but no response yet. Thanks!
