We've been using pyusb with the libusb-1.0 backend on linux and everything works well.
We're now testing on two windows 7 machines and are running into some issues. On one machine with libusb-win32 (i.e. libusb-0.1 backend) installed, pyusb works up until a point (we run into some timeout issues during reads -- but we think its probably a libusb-0.1 issue that won't be fixed). We are also only able to find our device, and only when we use a libusb0.1 driver. After upgrading our backend to libusb-1.0 by installing the WinUSB-libusb driver, we can't get pyusb to detect any devices e.g.: >>> usb.core.find(find_all=True) returns [] On a different windows 7 machine: >>> usb.core.find(find_all=True) returns a number of devices (usb hubs, etc -- including our device regardless if we use a CDC driver or the libusb driver). Anyone know what's going on? We're using pyusb v1.0.0b2 on both machines.
