I tried to run PyUSB under Windows and in a first test simply wanted to read out all my USB devices with usb.core.find(find_all = True). But that failed with backends iibusb0 and libusb1. Meanwhile I read several times that I need to change the driver of the device I want to talk to through PyUSB eg using Zadig. As I want to use the devices with different programs I can't change drivers. So my questions are:

• is changing the driver the only way to use PyUSB?
• what other options are there for USB under Python and Windows
• I downloaded USBTreeView and that runs fine - without changing any drivers. How does it do it? (I know its not Python) Thanks for any help Martin
