I have been using the CKB driver and until recently it is marvellous. I believe it automaticity updates the firmware.
Any guidance how to tackle the issue of keys frequently repeating? Doing an internet search recommendations are: Clean Keyboard (Done), Return to manufacturer (Maybe but not retained receipt and paid cash at GAME store, install earlier firmware (No clues how to achieve that under Linux?), change keyboard polling rate (Again ;No clues how to achieve that under Linux? Some articles covered that but were horrendously technical and way beyond my capability)
My capability is basically to understand and follow instructions by copying and pasting them into terminal.
I would be very grateful for any guidance here or a link to guidance. I narrowly resisted buying another keyboard today but as I have accumulated 9 keyboards (1 wireless, 6 Bluetooth and 2 wired) in my search for a comfortable one I want to stick with this as so far its the best other than the keying issue which drives me nuts (Especially when logging on with my password can take manyy attempts). Writing this I have had to correct about 40 words!!
