Corsair iCue Link Hub stopped being recognised by USB.

Hi folks, I need help with this. Had this system for a little over two years now and it's been fine. I currently have an iCue Link hub for my fans - this is connected via internal USB to my MB (MSI MAG Z790 Wi-Fi). My system is on the latest stable release version of Windows 11 25h2; all drivers are kept up to date.

The link hub takes care of 6 fans (no other components are connected to it). Here is a link to the product in question: iCUE LINK System Hub, Black

Today, when I turned on my PC, I got a pop up that said "Unknown USB Device (Port Reset Failed)".

Heading over to Device Manager, and the port my iCue Link hub is connected to is showing as "Unknown USB device".

I don't usually have iCue Software running (as I operate HW only settings), but I booted it up and the hub is also not showing up there either. (My RAM and my PSU do show up as normal).

Other observations: my fans continue to spin and light up as normal. I always use HW lighting and consistent fan speeds, and these appear to be still applied despite Windows having issues with recognising the device through USB.

What I've tried:

\- swapping the USB connector to different headers on my MB - this just moves the issue to another header, suggesting that this is NOT an issue with a specific USB header on my MB.

\- reseating the connections at the hub and MB end.

\- uninstalling the USB device from Device Manager and restarting my PC.

\- updating iCue / drivers.

\- reinstalling MB chipset drivers.


Nothing has worked so far. What can I try next? Seems a bit odd that my fans / LEDs continue to operate but Windows has suddenly decided to not recognise my iCue Link Hub.


Aside rant: the reason I’m posting here is that Corsair used to have community forums until they were shut down last August. The community forums were “moved” to Reddit and Discord - I’ve tried posting there about this issue and I’ve heard nothing back in over 24 hours. This simply wouldn’t happen on the Corsair forums, which was populated by knowledgeable and kind individuals who knew Corsair’s products inside and out -
Don’t you just hate it when a company destroys community lead support?

Nothing to worry about, I have several hubs that show as unknown however they work correctly.

Thanks - I’ve disabled notifications from Win explorer because every boot would show an annoying pop up about an unrecognised device.

Just wondering why this problem has suddenly occurred when it’s been fine for over two years?

Any any rate, my next set of troubleshooting tips are to
1. Buy a new cable (micro USB to 9pin MB USB) and test - I doubt this will work
2. Buy a new Link System Hub (they’re only £30 so not stupid money in today’s hardware sphere) - I think this should work.

Thanks for getting back to me :)

Well I have had others that fixed themselves and started being recognized.
Maybe yours will start again.

Do you mean a standard USB hub? My issue relates to a hub used to control my fans. It’s connected by USB, but it’s not a USB hub if that makes sense?

It is still the same principal.

Thanks for clarifying :)
