This adds support for pyusb dependency after v1.0.0b2 and brings a chance to rely upon the system pyusb package instead of a custom pip installation. By v1.0.0b2 the public API of the library has changed, and the 'interface' parameter from 'usb.Device.write' method has disappeared. This patch sets or avoids this parameter depending on the pyusb version used. X-original-commit: 312a161cacc7a04c2934a34ffb19cbf607462e69
