i am using one of the cheapest wireless keyboard available in our country (Zebronics make). It was working fine earlier. I was not using it for sometime (because i got laptop keyboard). I tried it recently it is not working.

the usb receiver is plugged in and i got a new battery. when i press certain keys multiple keys are being printed on the screen. can someone guide me on how to resolve this.

Try plugging your dongle into a different USB port.

I was researching on what was going on keyboard. Thought my keyboard is dead. I was researching on some split or ergo keyboard for programming related stuff. Now, i am able to conclude it is not available in India or it is very very pricey. So got an idea to remap my existing keys. This way i can work with the similar mods for future keyboards. there are many excellent works in this regard. decided to go for kbct, thanks to archwiki.

then i am able to run the test to figure out what is happening with my keyboard.

The laptop keyboard under event 23 (23) and the one wireless keyboard is MOSART Semi ...

Now when i press a key i can clearly see several unrelated keys are emitting signals.
