Continuing my #golang USB adventure. I am successfully "reading" from the device I'm playing with, after finding some variable alternates on the configured interface. I'm not getting any data, at any packet size. Assume this is because I have to tell the device to start sending data with a control request, however I can't get any to work. I even tried GET_STATUS which should be all zeros, but that gives me a libusb pipe error. The device is old, so USB1.1 spec is likely. reverse eng with 0 docs
