Yes, you're right, OpenUSB backend is not functional yet. I am giving it low priority because I don't see users claiming for it, so I am concentrating in make libusb0 and libusb1 more stable. I think in one or two releases I will get it working. -- Best Regards, Wander Lairson Costa ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
