Additional information about the device

No response

Can you help with implementing or testing the changes needed for liquidctl to support this device?

testing changes on Linux, attempting to capture USB/HID traffic, attempting to capture I²C/SMBus traffic

Additional Context. I couldn't find support listed for the Capellix XT models, but non XT models are discontinued and don't support AM5. Literally everything seems identical to the non-XT models except the CPU block has more fancy LED lighting (though its still just RGB, no LCD, though you can buy an aftermarket LCD to replace the cover with).

I can't imagine it requiring anything other than adding the VID:PID info to the database. The API stuff should be identical to the Elite Capellix non-XT.

I suppose that's worth a try. Since you haven't listed the IDs, can you please post the lsusb output, like this?

I'm sorry I forgot to mention that I was planning on buying this, saw that it showed as supported, but then I see now that it's in the supported devices list but has a line crossed through it?

I looked through the documentation, it says Core XT aren't meant to be used with AIOs, except that from what I can tell, the Elite Capellix AIOs COME with a Commander Pro XT specifically because they're ONLY for AIOs, you can't buy them standalone and a ton of their AIOs come with them.

Could you maybe let me know what the issues are? I'm not going to buy it if i'm going to be relegated to stock pump speeds or if it doesn't work at all and my CPU overheats, but if you can let me know what works, what doesn't, I suppose I could set a pump curve in the BIOS and then use liquidctl to control RGB and the fan speed, assuming those work.

Actually strike the Commander XT comment, but still, they come with the Commander Core, which should work fine. I just don't understand what's currently "broken" with those, when the entries for those devices don't mention any breakages.

It showed as experimentally and partially supported, and at some point it did work fairly reliably, although with the limitations shown in the docs. However, since then Corsair changed the firmware in a significant way, and we haven't been able to update our driver to match it.

This is currently being tracked under several issues, either because they appear to be slightly different bugs, or because they affect different devices in the family: #520, #583, #598, #623. That said, all devices in the family appear to be affected in some way or another, as far as I know.

Unfortunately the people that were directly working on this driver don't have the time to do it anymore, and the core developers don't have access to one of these devices. So we don't even know if the issues above are still relevant, or if there are new issues.

Contributions here would be much appreciated. Those interested in working on this might benefit from also checking out closed issues and PRs that deal with this family of devices, as there are interesting tips on how the work was done so far (including a memory dump script) which might not be referenced in the still open issues.

I haven't heard of a Commander Pro XT. Did you by any chance mean Core XT?
