Unfortunately the program in question uses libusb and the configuration only allows to define the device by specifying <busnum>:<devaddr> and there are multiple identical devices around with only iSerialNumber being different from each other. Somehow I need to make sure the devices in the USB hub are always recognized in the same order. I guess one solution would be to generate the configuration each time the program starts.
