Sounds like you need to brush up on how USB works. The host controller can talk to any endpoint on any device, and it schedules the transfers for them. There are no host-side endpoints like there are on the device. This question is very off-topic for this list. You should refer to the USB standards documentation or look for a USB specific mailing list. Please don't ask non-Linux questions on a Linux mailing list. g. -- Grant Likely, B.Sc., P.Eng.
