How to configure / troubleshoot a new keyboard

Solution 1:

It seems to me a hardware issue because there is a pattern in those working keys, this is compared to /usr/share/X11/xkb/symbols/us layout (may be you are using other layout)

   .. 04 .. 11         12
AE                     equal
AD    r                bracketright
AC    f     apostrophe
AB    v

As you see those letters are from same column, KP_* are from same block and same thing for control keys.

• May be the connector is misaligned
• Or they don't have same pins map (not same order for rows and columns in the connection).

Solution 2:

Have you tried to update ur system and usb ids?

apt-get update
apt-get dist-upgrade
update-usbids

Maybe this will help.
