USB Keyboard problem

USB Keyboard problem

[Itai Nahshon]

Just bought an "HP Multimedia Keyboard Hub" (USB).
Using with RedHat 7.2, kernels 2.4.9-81 and also
various 2.4.19-pre.

Immediately after boot the keyboard does not work.
I see some events from the knob and also from
some extra buttons but not from the keyboard itself
(some produce "unknown scancode" errors. That's
a different topic). The keyboard leds turn on and off
responding to pressing caps-lock etc on the PS/2
keyboard.

After "rmmod hid" and "modprobe hid" The usb
keyboard works just fine - until I disconnect/reconnect
it or until the next reboot.

The hub function on they keyboard works OK.

The keyboard works with other OS, or with the bios
(after I enabled "USB Legasy Support").

Any suggestions/hints?

I'm also looking for programs o test the HID event
interface (evtest) as suggested in the docs, It is not in
the suggested web page.

Thanks,

-- Itai

I don't know if this is the current/latest version or not,
but I found it in CVS of the Linux Console project at
sourceforge.net.  Browse the CVS here:

usb keyboard problem.

[LeVA]

Hi!

I have an usb keyboard, and it has some extra keys (internet keys,
multimedia keys).
If I use the keyboard in ps/2 port, all of those extra buttons work,
because I can bind the extra keys's keycodes in a hotkeys program.
If I use the keyboard in the usb port, some of the extra keys don't
work. In plain console, if I push some of the "non-working" extra
buttons, I get these error messages:

    keyboard.c: can't emulate rawmode for keycode 259
    keyboard.c: can't emulate rawmode for keycode 259

The problem is, that I can not bind keycode 259 in X, because it only
works for keycodes between 8 - 255. But when I use the keyboard in the
usb port, I get too high keycodes like (see above) 259, which I can not use.
I (fortunately) have a few working internet buttons. If I press those in
plain console, I get these messages:

    keyboard: unknown scancode e0 66

I don't think this is an error, because that key, which "produces" the
"keyboard: unknown scancode e0 66" message, works under X, and can be
binded to an action.

Is there any chance to make the keyboard work similarly in the ps/2 and
the usb port?

Please try to help me with this problem, I'm already through the
xfree86-list, and the debian-user list, but nobody could help me.

Thanks!

Oh yeah, it's pretty stock, as long as you
overlook the backported-from-2.5 scheduler -

Yeah. I am having a hell of a time with HP keyboards, and
I would like very much if you can help.

With 7.3 we roll a pretty stock 2.4.19-pre (called 2.4.18-4.x),
so there is practically no difference in this area. You may
be better off looking at stock kernels because the problem
is not Red Hat specific.

Yep. "rmmod hid && insmod hid" fixes it, and this is what
makes it hard to debug. However, your hint about the disconnect
is very important.

This is also needed for Linux: LILO or GRUB won't work unless
this is enabled. Kernel does not care, naturally...

It is linked from this bug:

Here's the link:

Please make sure that Vojtech is in the loop. I do not really
follow the input and HID code (after months of trying :).
