I also tried to run the FixIt renesxs from Support site and it just reinstall the driver for the controller but not the root hub.

I do have the sata rennesas connected. Joined Oct 6, Messages 46, 9. I have also disabled the legacy USB mode which didn’t help.

However, after roughly a few seconds, renfsas xHCI root hub simply disappear from the list and the opened dialogue box showed the device is disconnected but it is clearly sitting in the slot firmly.
