Linux Bluetooth Keyboard Connected But Not Working

Up until now, I could connect either a USB-audio headphone OR a USB-compliant MIDI keyboard to my USB-C iPad via a wired connection, but not both. This meant that one of the two – keyboard or headphone – had to be connected via Bluetooth. This is usually not a problem except when trying to record a live performance, where Bluetooth latency is frankly unacceptable. With the MiniFuse, however, both the keyboard and the headphone attach to the interface, and a single USB-C cable connects to the iPad. I have so many neat synth and other music creation apps on there that I can finally use live! This is HUGE for me. Note that the MiniFuse 4 supports up to 500 mA keyboards via its USB-hub, so long as it's plugged in, whereas the MiniFuse 2 supports only up to 250 mA devices, which cuts out most external USB-compliant MIDI keyboards. Yeah, it's a bit of a pain to have to plug the MiniFuse 4 to a wall socket to make it all work, but that's still just a single wire. Oh, also, I've connected some synths to the audio inputs, and I've been running both the headphone and main Audio outputs, as well as the loopback interface both with the iPad and my mac, and it all works and sounds fantastic. The manual takes a bit of careful reading to understand the possible routings (for me at least, I'm a newbie at this) but it's well written and I was able to figure it out pretty quickly. I didn't know I needed it, but now that I have the MiniFuse, I can't imagine not having it as the central hub to my synthesizer setup.

Gives all the buttons I need. And I don't look like a weirdo with a full bluetooth keyboard when working in a coffee shop.

But I'm moving to more Linux computing eco-system.

Check with linux and windows, in both working fine

Great mechanical keyboard for programming. Works great with Linux as well.

I bought this for my linux mint pc. It was as easy to get working as plugging it in.

Using this on a Linux Box. Got it working right off. I am very happy with this tuner.

Bluetooth pairs well with Windows or Linux on my laptop, and the USB adapter provides reliable fallback. The mouse fits my large hands, feels solid, and responds smoothly.

I use these on my android phone wirelessly (bluetooth) and with my linux computer wired directly through the motherboard line out for pc games, youtube, music, and disneyplus. I also use them wired into a surface go reformatted with ubuntu 22.04. Got them to work with bluetooth with the linux desktop computer but I don't actually have the SMA antennae attached to it so it is not really a fair test. (it is laggy, but it did connect and produce sound) They work great anywhere they are wired and wirelessly on android with wired connections sounding better. I don't really use windows often so can't comment on that at this time. I'm not an audiophile, but the audio sounds crisp with nice bass when watching movies with special effects. Music also sounds crisp and precise. They do fit fairly snugly but feel comfortable on the ears and are well made. I previously owned a pair of klipsch reference but these seem slightly better built. I consider them an upgrade in build and sound quality.

I've been using the Kensington trackball for a couple of weeks. It worked out of the box on my Linux machine and it's been responsive and reliable. The ball doesn't seem to clog quickly, and the button on the bottom to push it out for cleaning is a great idea. It works on Bluetooth as well as with their wifi dongle, which caused me some trouble when I switched it to Bluetooth mode by mistake, but when I finally read the instructions I quickly changed it back. It has buttons all over the place. I don't know how to program them under Linux nor would I want to, but fortunately they seem to do nothing if unprogrammed, as it's hard to use the trackball without clicking them now and then. This hasn't interfered with my use of the trackball, though. It feels much like the old Logitech Marble Trackball with a handmade tilted stand that I've used for years.
