Hello,

I tried this driver on my board and it looks like it's not supported

the Super IO is

currently I can't test under windows.

I checked the latest BIOS for this board (TUF-B450-PLUS-GAMING-ASUS-2008.CAP) and it doesn't have the WMI sensors interface.

Reopen this issue if it is added in a future BIOS release.

See this comment for how to check BIOS images https://github.com/electrified/asus-wmi-sensors/issues/11#issuecomment-515903663

@electrified : Hi, if I do a "dmesg |grep asus", I get this:

asus_wmi: ASUS WMI generic driver loaded
asus_wmi: Initialization: 0x0
asus_wmi: BIOS WMI version: 0.9
asus_wmi: SFUN value: 0x0

Yet, compiling and installing your code, I also get asuswmisensors: Vendor: ASUSTeK COMPUTER INC. Board: TUF B450M-PLUS GAMING BIOS version: 1804 WMI version: 0

Isn't it contradictory? Thanks for your work in all cases!

Hi there. The WMI sensors stuff has it's own version number which is an integer. I believe version numbers 1-4 are valid versions of the API that have been seen.

WMI sensors wasn't present in the 2008 UEFI image I tested in the previous message, it could be worth checking the latest 2202 using the method outlined in https://github.com/electrified/asus-wmi-sensors/issues/11#issuecomment-515903663, although it's very unlikely they've added WMI sensors support.

Indeed, WMI sensors are not found (looking for the SENX keyword) even in latest UEFI image (2202)
