I installed this firmware on my GMMK 2 (96 Key, ANSI):

> <https://github.com/SRGBmods/QMK-Binaries/blob/main/QMK%2BVIA-Firmware/0.21.6/gmmk_gmmk2_p96_ansi_via.bin>

I also added this plugin to both plugin folders:

> <https://github.com/SRGBmods/QMK-Binaries/blob/main/SignalRGB-Plugins/GMMK/_Archived/GMMK_2_96_ANSI_QMK_Keyboard.js>

SignalRGB just says this though in the Device Information screen:  
GMMK V2 96 ANSI - Glorious - 0x320f - 0x504b - None.

So the Plugin column is “None.”

How do I get this to work?

Plugin is already in Signal so if not showing something else sent wrong. look in  
C:\Users\XXXXX\AppData\Local\VortxEngine\app-2.2.33\Signal-x64\Plugins\QMK\GMMK  
use you own PC name in place of XXXXXX

You need to do a PID swap, to accomplish this you will need to do the following:

Change the following line in the Plugin file (line 4):  
export function ProductId() { return 0x505A; }

to this:  
export function ProductId() { return 0x505b; }

Then restart SignalRGB and it should detect the keyboard.

@Synomenon

Try the attached filed.  
Place the file on Plugins folder: [https://srgbmods.net/s?p=view/userplugins](https://srgbmods.net/s?p=view/userplugins) and restart SignalRGB
