Pimoroni Keybow - only works with another keyboard attached.

As the title states - been using a keybow on Pi4 for a while with another keyboard attached via a Logitech unifying receiver - all is good. However if I detach the unifying receiver and reboot the pi, the keybow ceases to work - latest fully updated buster image. Thinking of moving my setup to a 3a+...

Re: From where should i download raspbian stretch with desktop and raspbian stretch with desktop and recommended softwar

The current release is Buster. Why are you specifically looking for Stretch? (Every new major release *will* work on all older Pis. The newest models always require the--at the time--latest release. Thus, Buster will run just fine on a Pi3B+ but a Pi4B can only run Buster.) There’s always a wider a...
