Are there any fixes any firmware updates available for the Amikey A1200?
It works as intended. It was never ment to be used with a sum.
So what happens if used on a say a PC?
OK, now thinking, what are you trying to achieve?
Surely, if your connecting keyboard to amikey, then why are you using Amikey and sum at all. Surely your mechanical keyboard would connect through standard A1200 connector.
EDIT:- Will check on Firmware update.
