[pyusb-users] Assertion Error at End of Tutorial Test Script

[Sean K. <se...@gm...>]

Hi all,

I am currently trying to use PyUSB to interface with microcontroller in
order to automate some functionality.

There is firmware written and working for the micro.

However, I'm running into some problems implementing the test script
provided at the tutorial here:

https://github.com/walac/pyusb/blob/master/docs/tutorial.rst

I brought the test script into an editor, and changed the vendor and
product id, as well as the test string sent (I changed 'test' to 'V L',
which will light an LED on my development board).

When I run the script via powershell (Windows 7 64bit), I get the following
traceback error:

PS C:\...\PyUSB Dev> python simpletestscript.py
Traceback (most recent call last):
