Is there a list of compatible USB keyboards/chipsets ? I got a Lenovo ThinkPad Compact Keyboard (KU-1255) to work but my GMMK Barebones does not work (I tried different cables and different hubs).

Edit: Got a couple keyboards yesterday from Logitech and those worked. I assume the GMMK keyboard may not have a standard implementation of keyboard device. Realized I needed a full keyboard anyway and got a Logitech G413 SE (YU0074)- that worked. Logitech K400 Plus (Y-R055) worked also and used a wireless usb receiver that can be setup with other keyboards so I suspect the wireless USB Logitech standard will work other Logitech wireless keyboards. Made a table below with USB vendor and device IDs for anyone else interested:

Code:

Keyboard         | Vendor ID | Device ID | Compatibility
-------------------------------------------------------------------
GGMK-TKL-RGB     | 0x0C45    | 0x652f    | No (Microdia/Sonix Vendor)

Lenovo KU-1255   | 0x17EF    | 0x6047    | Yes

Logitech Y-R0055 | 0x046D    | 0xc52b    | Yes (unifying USB wireless receiver)

Logitech YU0074  | 0x046D    | 0xc349    | Yes

Yes it seems to me that the GMMK is not a normal Class Compliant HID (Human Interface Device) but needs a driver to set it up. Those kind of keyboards are not usable in the most cases. There is no list of what works and what not. I know only about one Cherry Keyboard which didn't work but which does work using a USB hub.
