can't set colour on keyboards backlight but can on case lights light

[wbrown766]

So got this laptop a while ago and tried to set this up when I first put Linux on it... TLDR: didn't have time to play properly like I just thought I hadn't installed it right or something stupid.

So the time has come.

Im currently test driving Linux Mint 20.3 on a TongFang GM7MP0P which isnt on the list of compatible devicesm but what the heck they can't be that diferent.

So I done a fresh pip3 install.

Tested functionality:

• could set some styles
• could no set any colours
• brigthness works on the few styles that do work
• speed works on the few styles that do work

I looked through the known issues but no joy.

However I did notice that sudo hwinfo --short outputs 2 devices and lsusb confirms this with 2 different IDs so its not a glitch in the matrix.

I changed this line in the main.py file

165 |        control = ControlCenter(vendor_id=0x048d, product_id=0x0xce00)

to

165  |        control = ControlCenter(vendor_id=0x048d, product_id=0x6005)

which after a reboot made my case lights light instead of the keyboards backlight.

WHAT.... I DIDN'T EVEN KNOW THIS THING HAD CASE LIGHTS.

Tested functionality:

• could set some styles
• could set colours
• brigthness works on both colours and on the few styles that do work
• speed works on the few styles that do work

After this I really don't know what to try as I can't see it being a problem with your current code, any suggestions?
