Problem with keyboard on CoolerMaster Quick Fire Ultimate.
Hi everyone, I'm experiencing some problems with my CoolerMaster Quick fire Ultimate keyboard. When trying to change the lighting controls (Fn + F1/F2/F3/F4), the keyboard stops working and shows a message that the USB device is disconnected. If I press it during startup, the whole PC crashes. All other keys function normally and don't cause issues, even when adjusting the backlight. Only the LED backlight changes. Any suggestions?
