Hi,
I have just purchased the Keyrah V3, and am extremely grateful that this hardware exists to allow me to combine 30+ year old tech with modern day equipment.
I am currently building an A500 Maxi of my own, and have a working A500 keyboard attached via Keyrah to a Raspberry Pi 4.
Firstly, I just want to be clear that I know there is not a hardware fault with the Keyrah V3 or the A500 keyboard. The A500 keyboard when connected to my Windows PC works flawlessly.
The quirky issue I have is when attached to the Pi:
- When the caps lock is off (LED off) and I type, lowercase letters are produced as expected.
- If I hold the shift key down, still with Caps Lock off, uppercase characters are produced as expected.
- When I put the Caps Lock on, I get a mixture of uppercase and lowercase letters, for example pressing the keys 'a', 'b' and 'c', may well output AbC.
As I say this activity is ONLY happening with the Pi and Linux distros.
What I have done so far to test the hardware etc is fine:
- Connected to Windows PC - everything is fine, and every test combination with Caps Lock on or off works
- Tried two different Raspberry Pi 4 devices - same result
- Tried two different distros of Linux - Ubuntu and DietPi - same result
- Tried connecting the Keyrah device to the Pi via a powered USB Hub to rule out power issues with the Pi. - same result
The above suggests there is no hardware issue with Keyrah, the A500 keyboard or the Pi(s), it seems a possible software/firmware issue, or I am being realy stupid and doing something wrong!
Any help would be greatly appreciated.
Thanks
Andy
