CORSAIR iCUE Commander ST

[zzjas]

Hi, I recently purchased a CORSAIR - iCUE H150i ELITE CAPELLIX CPU Cooler from Best Buy. Though in the description it says a "CORSAIR Commander CORE" will be included, I can only find a device called "CORSAIR iCUE Commander ST". Would it be possible to control the Commander ST with liquidctl? I'd be happy to assist if any help is needed. Thanks!

Here's the device information from lsusb.

Adding USB ID to commander_core driver allows reading data from the device just fine.

CORSAIR iCUE Commander ST

This device is no core.
Can't find anything to this device it's like it don't exist.

The reason why we currently consider this to be a Commander ST comes from the initial description of the issue:

Though in the description it says a "CORSAIR Commander CORE" will be included, I can only find a device called "CORSAIR iCUE Commander ST".

And the fact that both of the product descriptors bellow can be observed for the same VID:PID:

Bus 001 Device 007: ID 1b1c:0c32 Corsair CORSAIR iCUE Commander ST
Bus 002 Device 002: ID 1b1c:0c32 Corsair CORSAIR iCUE COMMANDER Core

So this is some type of Commander Core variant. But perhaps it's not fully compatible with previous Commander Core variants (Core and Core XT).

I've got one of these, if anyone needs someone to test stuff on I'm willing and able :)

Does anyone know how to turn the ludicrous LEDs off (permanently, without Windows) on the 1b1c:0c32 device?

With liquidctl 1.12.1 I'm doing things like:

$ sudo liquidctl -n 1 set led color 000000
ERROR: Corsair Commander ST (experimental): operation not supported by the driver

but no incantation seems to work and the man page isn't unfortunately that helpful.
