Description Arnaud Kleinveld 2017-01-21 07:38:33 UTC

Description of problem: At random moments in time the mouse pointers lags and moves choppy. Not every day. When it happens it's back to normal within a few minutes.


Version-Release number of selected component (if applicable): 4.8.15-300.fc25.x86_64


How reproducible: It happens randomly but occasionally it seems to be caused by increased wifi connection usage.


Steps to Reproduce:
1. Wait until it happens. Not sure if it happens every day.
2.
3.

Actual results: At random times a lagging pinter and choppy pointer movements


Expected results: Fluent pointer movements

Comment 1 Arnaud Kleinveld 2017-02-05 08:45:00 UTC

It looks I have solved all my bluetooth mouse issues by providing a firmware patch at /lib/firmware/brcm

I discovered the following 2 error messages:
bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-216f.hcd failed with error -2
bluetooth hci0: BCM: Patch brcm/BCM20702A1-0a5c-216f.hcd not found

Googling the error lead me to a site explaining how to extract the patch from an MS Windows driver.

No that I have installed the patch I have no more disconnects and lagging for a few days.
