usb xhci compliant host controller code 39

Installing the USB31_PT driver and USB31_PT_HUB driver, version 1.0.5.3 from the AMD Chipset drivers allows the controller to run at correct speeds.The AMD compatible driver is availabe in the AMD chipset drivers here.The AMD compatible driver is not available in ASRocks All In 1 Driver package for B450M Steel Legend.The Microsoft USB xHCI Compliant Host Controller driver causes it to run at USB 2.0 speeds.Others have taken to modifying the USB30_ZP driver for the Pinnacle CPUs so they can get the driver to work with this controller.There is no AMD compatible driver for Windows 7, however the Microsoft default one does work.Is there anything I can test to confirm its working properly? Windows Device Manager doesn't show any missing drivers. I have not tested the USB C connector Gen 2 port, I don't have a USB C to USB C cable.Ĭard reader plugged into USB 3.1 Gen 2 A port - Ĭard reader plugged into USB 3.1 Gen 1 A port. But only runs at USB 2.0 Speeds when plugged into the Gen 2 A port. Using USBTreeview, I tested and confirmed the card reader runs at USB 3.1 Gen 1 speeds when plugged into any other USB 3.1 Gen 1 port on the motherboard. I've tried testing my Oculus rift and Oculus quest and a Transcend USB 3.1 Gen 1 Card Reader ( I know its not Gen 2 but I would expect it to run at Gen 1 speeds ) The USB 3.1 Gen 2 A port on the back of the motherboard is running at USB 2.0 Speeds. Anyone else had this issue? I've put in a support ticket with ASRock
