I did only check whether the device with its four channels are registered. Since the chip is built-in on our board and I still need some additional libraries to check the devices connected to it. I haven't done a= ny function tests still. Will keep an eye on this. Sounds that it could be a l= ittle hairy then. Afais the PID 6001 is e.g. shared by common/high speed devices.= I didn't grab deeper in the ftdi code, probably it'll be some way to work aro= und this. cheers Luotao Fu --=20 Pengutronix e.K. | Dipl.-Ing.
