I have manjaro as my operating system and my wireless keyboard is not working with usb or bluetooth. the bluetooth way, it types after seconds i pressed any button. I found this page https://linux-hardware.org/?id=usb:0e8f-00a7 but I dont know how to download or anything.
I found out later in life that the keyboard I used was not a legitimate hardware designed from the company (other Bluetooth devices work perfectly), and the USB dongle was exchanged with another hardware.
