Other Parts Discussed in Thread: TUSB2046B

Kindly assist to advise on the issue faced. When testing “Port Remote Wakeup”, the controller doesn’t return the correct status when a suspend command is sent to it and likewise status is not returned correctly when a remote wakeup event happens. Is remote wakeup supported for this controller? Thanks..

    A USB hub is not usually a remote wakeup event generator - this is usally done by a peripheral device such as a mouse or keyboard.

    The TUSB2046B is not capable of generating remote wake-up events, but it does pass through a remote wake-up event generated by a connected downstream peripheral up to the host controller.

    What operating system are you running?  What is your host system?
