Rog Crosshair X670E Hero - USB Device over current detected

Level 10

Hi everyone, I have an Asus ROG Crosshair X670E HERO motherboard and this board has 2 USB 3.2 Gen 1 connections inside.

I connected one of these connections to the front USB C port of my case, however, every time I turn on the PC and connect a USB C peripheral to the front port of the case, the BIOS gives me this error message: "USB Device over current detected".

Anyway the problem seems to be only in the BIOS when the PC boots, because when the PC is in Windows 11 the USB C port works flawlessly with any USB C device connected.

That said, it seems to be more of a bug in the motherboard's BIOS, I installed version 1602.

Has anyone else encountered the same problem as me?
Thanks in advance for your answers.

1. Are you connecting the USB C ports supplied with the chassis? If so which manufacturer and model.
2. If the prompt is only present when a device is connected to the front panel - what device are you connecting?

1. yes, model: Lian Li - O11DXL 



2. the defect occurs by connecting any USB C peripheral: smartphone, USB hub, Gamepad...



Try connecting the 6 PIN PCIE to the PD_12_Power connector, as this is needed for Quick Charge functionality (up to 60W).

Can you please tell me and show me exactly what type of cable it is?

Can you give me a link to where I can buy it?



It's a PCIE 6 pin, will be the same connector you'd use for the GPU. Depending on your PSU, you should have one spare. If not, specify you PSU make and model so we can locate one online.
