PS/2 port on USB Keyboard

[Emmanuele Bassi]

Hi everyone,

I have an USB Keyboard from BTC[1], with an onboard PS/2 mouse port.
When I use one of the mouse' buttons, the kernel complaints (with
a .warn):

keyboard.c: can't emulate rawmode for keycode 27[2-4]

The keycode depends on which mouse button I press (272 for the left,
273 for the right and 274 for the middle one). While I'm using the mouse
under X11, this warning goes straight into the logs, but while I'm
under the console, this warning scramble up everything. A possible
workaround is to disable every kernel.warn directed (via syslog) to the
console, but, for obvious reasons, I'd like to keep this as a "last
resort" option.

While looking inside the source code for the Keyboard HID driver, I've
noticed that only the Mac driver enables mouse button emulation. Since
I'm no kernel hacker, my question is: could someone work on a possible
patch?

TIA & best regards,
 Emmanuele.
