I have a Z590 Gigabyte Master with USB 3.2 gen 2 support. There is one USB 3.2 gen 2 port on the back and one USB 3.2 gen 2 port on the system board. The port on the system board header is 1 lane and the back port is 2 lane. Is there a SIV display that shows the lane allocation for USB 3.2 gen port? Is so, which display selection?

Given you are asking about USB I feel you should have posted the [USB Bus] screen shot from your system and it's always sensible to specify which Windows build you are using. What SIV reports depends on which bits are set in the USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS so it all depends on what Windows reports which I suspect will be different for different builds of Windows. |

Windows 10 Pro build 19042 There is a screen (PCI bus) that does show one USB device with 2 lanes negotiated. This might be the device in question but I can't find a way to tie it back to a specific USB labeled storage device. The Z590 Master manual on page 7 does show the USB 3.2 gen 2x2 support. I only have one of these ports. This port is correctly working with a USB 3.2 type C connected NVMe storage device. I have the same question when of associating a specific USB port to a USB storage device and how many lanes are assigned and negotiated. |
