On Linux, it works with USB cable and wireless RF-dongle modes, but not with Bluetooth mode (still it connects fine). We did monitoring with btmon and apparently it gets an events, so the problem was considered on HID level. See btmon logs and conversation here: https://www.spinics.net/lists/linux-bluetooth/msg96904.html I'm trying to understand if the mouse speaks some proprietary protocol and we need additional driver for it, or it's  just generic HID mouse and it doesn't work because of bug somewhere in Linux HID stack? Could someone give me a clue? Thanks.
