Re: ukbd patch advice

As suggested by Andrew Thompson, I have attached the patch
for ukbd.c to show the changes I've made.

Hey all,

I have been having a problem with my particular usb
keyboard (0x03 was always being written into the first
element of ukbd_data->keycode basically). I have tracked
it down to a problem somewhere in between the uhci chipset
(same problem with other cuts of uhci chipset), the uhci
and/or ukbd drivers and the keyboard.

A fix to the problem is to reorder members of the struct
ukbd_data. Originally, the members are ordered as
modifiers, reserved and keycode[6] (minus a bunch of
#define's). If I change this order to reserved, modifiers
and keycode[6], my keyboard starts to function as it
should (minus lighting up the LED's but that's another
email all together :)). With this reordering, it stops
other usb keyboards which function with the original code
from working.

I'm wanting submit a patch for this fix (as other people
are experiencing the same problems) but I'm not sure how
to do this. I was thinking along the lines of the usb
quirks function but it appears outside of a function body,
you cannot have the normal if() type statements, only the
preprocessor #ifdef types. To me, having a kernel config
option for a single keyboard on a single driver seems
quite overkill.

Does anyone have any suggestions on what I should do or
can anyone point me to some code that deals with a similar
problem?

On a side note, is anyone able to shed any light into why
they think the above fix works? I am drawing a bit of a
blank to be honest. Is it possible that my fix is only
masking the problem?

If you need any more info or whatever, yell out.

Cheers,

Sam.
