I wonder if it was an edge case that the Linux driver didn’t account for, like a minor incompatibility between the two devices.
You’ve just reminded me that I had a Bluetooth problem with my laptop a few years ago. My headset would connect and work properly, but wouldn’t be recognised after the laptop had either been to sleep or shut down. I had to go through the bluetooth device folder, something like /dev/bluetooth/, find the folder that corresponded with the headset’s address, and delete the cache folder inside. It would then work until the next sleep / shut down.
I expected problems with the Pi because USB wifi has always seemed to be a bit dodgy, even on Windows, and wifi is apparently still a problem area with Linux. Add to that the Pi’s limited distro, and I thought it was bound to go wrong.
Thanks for replying :)
I’ll have a look into it, thanks. I pretty much only support my mother’s laptop outside of my house now, but I use NoMachine to sort out the home computers. As much as I like it, it can be a bit slow sometimes, and it’s always in the back of my mind that it’s going to lock me out like the others did.
