Description Alexandre C. Guimarães freebsd_committer 2017-04-14 16:43:42 UTC

I have a "Microsoft Wired 600" keyboard and the numeric pad dot, ".", is not working at all, neither on console or X.

I opened a thread on forum and someone come up with the same problem with a ABNT2 layout keyboard, but different model/brand (MaxPrint):


It seem the numpad dot key is not generating a scan code and also have the interrupts ignored.

I do not know if Media keys also belongs to the same bug report because it is a hid device, but my specific keyboard have five XF86 keys (Play/Pause, Volume Decrease, Volume Increase, Mute, and Calculator).

While trying to configure them using sysutils/uhidd I find out one of the media keys randomly do not work after every boot (but the calculator, what always work), apparently with the same problem as above, but, as said, on a random Media key - and just one.

Also, some time ago I found another person on #freebsd with similar problem with Media keys, but for that particular person it seem all XF86 keys working do not work, however I do not know more details about keyboard model or layout.

PS. I am not sure about the right component to blame.

Thank you!

The problem is still present in 11.1-RELEASE, in a upgraded installation and in a fresh one.

I would just like to add: an installation what was updated from 10.3 to 11.0 did not suffered of this issue, but after a fresh 11.1 install, that installation began to suffer of the same problem.

The behavior is the same using sc or vt.

ABNT2 numpad image.

The ABNT2 numeric pad is slightly different of the majority of the others layouts, and so I attach a small image of that.

Based on some talks around, it seems to also affect the Portuguese keyboard.
