With patch "HID: logitech-dj: add support for the new lightspeed receiver iteration", the mouse starts to error out with: logitech-djreceiver: unusable device of type UNKNOWN (0x011) connected on slot 1 and becomes unusable. This has been noticed on a Logitech G Pro X Superlight fw MPM 25.01.B0018.
