We have been using pyusb with our custom usb devices with mostly success.
We've run into an issue though that only occurs on a specific windows 7
machine. The device is not found with a call to
usb.core.find(find_all=True). The other usb devices on the machine (hubs,
etc) are found -- so pyusb must be loading the backend correctly.
We've tried installing the device drivers for libusb-win32, libusbK, and
WinUSB -- all with the same issue. The machine with the problem is Windows
7 amd 64-bit. Our other Windows 7 machine (on which everything works fine)
is also a WIndows 7 64-bit machine, but with an old intel celeron processor
-- so perhaps the processor architecture has something to do with it?
Has anybody encountered anything like this? Or does anyone have any
debugging tips -- like logs we could access or debug flags we could enable?
