This happened to me as well. I noticed that if I called USBDeviceOpen(), or USBInterfaceOpen(), I'd usually get an error on the first call. Just to be stubborn, I tried calling the open command again after it failed, and it opened successfully.

I don't have an explanation for it (possibly uninitialized variable?), it works, so I moved on. At the very least, it's an idea to try.
