As per Jonas' reply, its not clear libusb has been installed. zadig works

This is not true.
The solution, as you have already gathered, is to install libusb.

You probably want to delete this file and try again.

Take note HID is only using Interrupt Transfer. And Isochronous

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

So the problem is that your Python is 32bit whereas by default libusb-1.0

Happened to come across the solution to this. Simply build libusb with
./configure CC="gcc -m32"

Yes, libusb must be installed separatelly from PyUSB. I will add an
install section in the docs,
sorry
By the fact that you are asking what libusb version I am using, I assume I
was supposed to install libusb independent of pyusb? I didn't catch that in
the docs...
If so, which libusb do you recommend I install for win32? I looked at
libusb-win32:

I guess it is a libusb build issue. Try to build and run any of the libusb
samples.

See below for the debug trace. Looks like it finds libusb-1.0, but
claims that it was built using the wrong architecture. When installing
libusb-1.0, I downloaded the source then ran
./configure;make;sudo make install

Ok, try to create another env variable:
export PYUSB_DEBUG_LEVEL=debug
And send the results. PyUSB will start to dump debug messages on the screen.

I've tried adding /usr/local/lib to both $PATH and $LD_LIBRARY_PATH (I
had to create the latter), but no luck; the error persists.

Hi Mike,
What about your library path? Does it point to /usr/local/lib ?
