Logitech G710+ not working

[Flawnex]

I had an issue earlier with some driver file left by Comodo giving me a BSOD when I launched GTA5 (cmdcss.sys) which I deleted. After that the only things working on the keyboard are the lights, macro keys and USB-pass thru. I've tried reinstalling drivers, testing USB slot and using the keyboard on this laptop (it worked fine). Ask me any extra information you might need to fix this.

Thanks for all the helpful responses. Here's the fix: Find some registry class key named UpperFilters which is referencing cmdcss.sys even though its deleted and replace it with kbdclass. Also I heard that if you have LowerFilters you should delete it. Might be worth to check your class registry key even if you haven't used Comodo products.

Located in: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318} (There are multiple with the same name, look for the one that says Keyboard anywhere in the registry)
