USB-C port not working

I have a desktop with a CORSAIR 4000D case. There are two USB ports on the top front - one of which is USC-C. Theis USB-C port is not working in that any drive plugged in there there .shows up on the Windows Explorer. Does any one have any suggestions on how to check for any faults or even resolve it?
If it is relevant I am running Windows 11 Home (I am finding that this has limitations on what you can do system-wise).
Thank you in advance for any help you can give.

Do you mean to say that the drives plugged into the port don't show up in Explorer?

Can you post your full system specs? I'm presuming this is a PC Specialist system...

What drive are you plugging in? Is it definitely USB c and not thunderbolt as the two use the same physical connector but they're different.

It never has worked.

How do I tell the difference? Thunderbolt is not mentioned in the specs.
I have looked on the Device Manager and can't tell which port is supposed to be USB-C but looking on the internet, it seems you can't tell the difference (or is very difficult to do so).

What make and model is the drive?

On the drive port, if it's thunderbolt it will have a lightning symbol next to it:

It has never worked. I have tried two different cables, bot of which connect fine to my laptop.
I can also successfully use USB-C to USB3.0 cable to attach to the square-type USB port next to it.

Hang on....I have just taken delivery of some new cables. I plug it in and up pops a message
"Power surge on USB port. Unknown USB device needs more power than the port can supply".
I am trying to connect a Samsung T7 SSD, and the casing shows 5V 1.5A. Surely this is not particularly high spec for what should be high speed port? If so I will be a bit peed off.

Ok so it's a Samsung T7

So it is USB

Trace the cable from the case port to the motherboard and make sure it's properly inserted into the correct port.

PS - the USB-C plug is very loose in the socket so could this be the reason? (the USB is also yellow coloured on the inside, whatever this means)

I have attached some photos: one showing the ports on the top of the casing, one of the plugs underneath on the inside of the casing (they line up with the USB, not with the power switch), a picture of the right hand panel inside showing the track of the cables, a close-up of the end of the USB-C cable end and a close-up of the USB-A attached to the motherboard. All plugs as they are are firmly seated
So there are the three cables coming from inside the top panel of the case:
- A flat cable, goes out to the right, halfway down the right hand panel then loops back into the left hand side and attaches to the motherboard (socket U32G1_78)
- A round cable that comes from the USB-C socket down the right hand side and terminates in a loose plug seen in the close-up
- A second round cable that comes from the panel of pins and dives under the motherboard to a block in a separate cage.

It puzzles me that the USB-C cable is not attached to anything but I still got that 'not enough power' warning - unless a basic power supply is there but cannot do much else.
Next to where the USB-A connects to the mother board is a socket labelled 'U32G2_9'. Is this where the USB-C should be?

Looking at the motherboard specs on the ASUS website, it includes "front USB 3.2 Gen 2 Type C" so I am guessing the port should be supported.

My guess is that the USB C was dislodged when the motherboard when the internal protective packaging was removed.

The not enough power is down to the cable, it's just saying there's not enough power, or none in this instance.

A USB C motherboard header is it's own connector, won't fit in any other port. You just need to plug that back in. If it fits that U32G2_9 port them yes that would be it.

And BINGO! There we have it - all working now. Thank you so much for your help.
The frustrating thing is that the USB cable was cable-tied in with the other round cable - so it was not that the plug had fallen out but that it was not connected in the first place.
Thank you again for your help. One happy bunny!:D

Oh, in that case then yes, sounds like the builder missed that part which isn't great, but well done for sorting it.

It's a decent build, should do you right for a long time (y)
