Hello, I installed the B550-HDV motherboard in an old case that has a front USB 3.0 port. (Specifically, this case: https://support.hp.com/us-en/document/c05681331" rel="nofollow - https://support.hp.com/us-en/document/c05681331 ) The port worked fine when connected to my old motherboard in this case. That motherboard had a connector for USB 3.0. (Here: https://support.hp.com/us-en/document/c05634309" rel="nofollow - https://support.hp.com/us-en/document/c05634309 ) The connector itself looks identical to the following connector on my new ASRock motherboard called: USB 3.2 Gen1 Header (19-pin USB3_5_6) However, the USB port doesn't work. I am curious if anyone can offer guidance on troubleshooting. Thank you! |

Hello Is the USB3_5_6 port on your B550-HDV working correctly when you use another front panel or rear bracket? ------------- X399 Taichi (4.03) Threadripper 2950X DDR4 2 x HX432C16FB3K2/32 |

Thank you for your reply! Good suggestion. To my knowledge, I have no other way of testing the USB3_5_6 port is functional at all; I have nothing else to connect it to. (There is also a "USB C" front port on the case, but I don't have anything that's USB-C on both ends to see if this would work.) I think (??) I have found an explanation - per the below thread, HP cases use a non-standard layout for its front USB ports that is only compatible with its own motherboard. That is, the front panel itself is plausibly the problem. https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Kaili2-Motherboard-USB-3-0-pinout/td-p/6809577" rel="nofollow - https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Kaili2-Motherboard-USB-3-0-pinout/td-p/6809577 |

It seems the USB 3.0 port in your old case isn't functioning with the new B550-HDV motherboard. Despite the identical appearance, there might be compatibility issues. First, ensure the USB 3.2 Gen1 Header is correctly connected. If the problem persists, consider checking for BIOS updates or consult ASRock support for further assistance. ------------- mya |
