I have a Razer Deathradder v2 x hyperspeed bluetooth mouse does not appear in the bluetooth tab. it only works with 2.4ghz receiver.
I am using Toad IV and I am having exactly the same issue.
I am having Fedora dual booted with Win 11 and the mouse works perfect in Toad IV as well as Toad IV Plus bluetooth modes, in the case of windows only.
As I infer this could be a missing driver in all the linux distros i have tried?
I have tried to connect to my mouse in garuda linux, arch linux and ubuntu… and the case is the same there as well.
EDIT
I found a little stupidity that I did, after switching from windows to linux, i forgot that the mouse itself needs its button to be pressed for approximately 5 seconds to go into pairing mode. As soon as i did, the mouse was shown in the list and eventually it works very nicely.
