Description Ivan Kalvachev 2019-07-28 14:20:44 UTC
https://bugzilla.kernel.org/show_bug.cgi?id=203369 "A4Tech mouse: horizontal scrolling is recognized as vertical since kernel 5.0" is fixing a regression.

Unfortunately the fix itself causes another regression, that prevents *some* a4tech mice from using their vertical scroll.

There is already fix for that here:
https://www.spinics.net/lists/linux-input/msg61859.html

The fix works for me and a number of other people who have similar issue.
However the fix doesn't seem to be merged or pushed upstream and has been forgotten and ignored for almost a month.
The regression is still present in 5.2 and 5.3 branches.

Please apply the fix.

I can confirm that patch is not implanted into 5.1.20 or 5.1.21 [EOL] kernels and thus this (small, but annoying) bug with A4Tech mouse is still present. I observed freshly new 5.2.5 kernel changelog, but it looks like this patch isn't included here as well.

Please apply the fix, thanks!

New kernel 5.2.6 is freshly on the scene. I'm reading the changelog and it looks like nothing is changed with this issue :-(
Comment 4 Ivan Kalvachev 2019-08-31 16:03:13 UTC
The fix has been merged in linux-5.3-rc4 , so it would be available in 5.3.0 release.
It also has been backported to linux-5.2.11.

I don't think they would be releasing any more revisions of linux-5.1.x ,
so I consider the bug fixed.
