I do not know how to do this. So it's not AsMedia host? Regardless, if the patch allows the host to see SuperSpeed Plus hub, then it confirms the host controller reported the wrong port speed ID in its root port. The patch gets the speed from device notification instead. The device notification sublink speed should be propagated for devices under the hub. The fact that you still see 5Gbps means there are other problems either due to the host controller or the hub. > > If anyone is able to help with a manual kernel patch to test other then the one > in the comments here then I'm happy to test. > > Thankyou. > It'd be better for the vendor to provide the support and patches to resolve this since they have the knowledge and the tools to debug their hardware. I can only provide clues for whoever needs to proceed further. BR, Thinh
