IIRC I've only seen this quirk with the oddball VID/PID 7545:0104 that my patch 7/7 adds. It is indeed a USB-only controller. I have not tried this device (or any, really) with an actual console, my focus is just on Linux. Admittedly, I'd also like to know what happens on a real PS4 :)

My intention was to keep the error message and the solution as universal as possible, in case a controller comes along that has both this quirk *and* Bluetooth. It's a bit of an ugly workaround though - if you (or anyone else) have an idea for a nicer solution, I'd be really glad.
