im currently struggling to pair MX mice (anywhere S2 and S3) and keyboard via bluetooth in endeavourOS. works okay with intel ax-210 chipaet/driver on one machine but on another machine i can only get both to pair to a bluetooth 4 (le) dongle but not bluetooth 5+ chipset (realtek or intel 9560). not sure if bluez bug or btusb driver or smth :( any tips?
