I don't know if this is helpful, but I have an MSI B450 Tomahawk Max, |
| 10 |
and the USB3.3 headers that I route to front-panel connectors work fine. |
| 11 |
I just plugged a USB3 flash drive into one of them: |

I also have two USB2 connectors on the front panel. |
| 31 |
|
| 32 |
All total, there are |
| 33 |
|
| 34 |
2 x USB2 in back panel |
| 35 |
4 x USB3.2 in back panel |
| 36 |
|
| 37 |
4 x USB2 on two dual-port 10-pin headers |
| 38 |
2 x USB3.2 on one dual-port 20-pin header |
| 39 |
|
| 40 |
It appears that I have a total of 6 USB hubs on the motherboard: |

It looks like you should have two 20-pin USB3 headers on your |
| 51 |
motherboard (mine only has 1). Are you sure your front-panel |
| 52 |
connectors are plugged into a USB3 header and not one of the 10-pin |
| 53 |
USB2 headers? |
