I have a ps2 keyboard that has a scroll wheel on the side, it doesn't work on Ubuntu 12.04 so I though to just check xev and map the correct key. But xev doesn't show up anything when moving the scroll wheel.
The keyboard is this one (A4Tech KBS-26), it works fine on Windows without adding any extra driver. On linux most buttons work, multimedia, calculator, browser, etc. The only thing that doesn't work is the scroll wheel and copy/paste/cut/undo buttons, and they don't show up on xev either.
Does someone knows how to make it work?
Update:
I found this with dmesg command:
When moving the scroll wheel up:
atkbd serio0: Unknown key pressed (translated set 2, code 0x8b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e00b <keycode>' to make it known.
When moving the scroll wheel down:
atkbd serio0: Unknown key released (translated set 2, code 0x8b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e00b <keycode>' to make it known.
"xmodmap -pke | grep croll" shows:
keycode 78 = Scroll_Lock NoSymbol Scroll_Lock
keycode 185 = XF86ScrollUp NoSymbol XF86ScrollUp
keycode 186 = XF86ScrollDown NoSymbol XF86ScrollDown
How do I configure it so when "pressed" is keycode 185 and when "released" is keycode 186?
