So what i have done since is: Downloaded and copied the firmware as advised by You-Sheng Yang (vicamo). Rebooted and then tried again, time was slightly less in waiting.
I then removed blueman again just in case that was giving issues and reattached the mouse via bluetooth (reboot again) with the same result. And on the issue with the touchpad, it works fine, i also disabled it via the bios and used a wired mouse and that works fine. I'll be getting another wireless mouse to test tomorrow. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1886245 Title: BCM20702A bluetooth mouse freezing for 4-9 seconds Status in linux package in Ubuntu: Incomplete Bug description: Boot system, the Bluetooth mouse will stop for about 4-9 seconds, then it will work as normal.
