Does the manufacturer's proprietary software run under the embedded board? If yes, then you have to identify the differences between the proprietary software and your pyusb application. If the proprietary software runs under a normal Windows PC and not the embedded board, then you may have to concentrate on the embedded board again. When you tests its functionality in code temperature, did you run the tests with some USB peripherals? -- Xiaofan ------------------------------------------------------------------------------ Announcing the Oxford Dictionaries API!
