USB Keyboard Problem, some keys produce multiple keystrokes

Hello,

As the subject states, I'm having trouble with a newly purchased USB keyboard, which is replacing the PS/2 keyboard I had before (I'm doing this
becuase I want to use a KVM switch).  I have checked that the keyboard still produces multiple keystrokes even if directly connected (not connected via the KVM switch).  The keyboard also came with a PS/2 adapter, and it still doesn't work right, in exactly the same way, if I use the adapter.

in particular, the number pad digits 2 5 adn 8 as well as the "right arrow key" produce multiple keystrokes:

(all these keypresses / key events are keypad events, as tested in xev)

2 = 2 3
4 = 5 6
6 = 8 9

(this is the right arrow from the cluster of 4 arrows between the main keyboard and numberpad)

rightarrow = Right KP_Subtract

I'm not sure that this is an exhaustive list of keys that are not functioning, but most of the other keys work fine.

this is a problem both in tty1 - tty6 and Xorg.

Here's some info on the keyboard model:

It's a "Dynex" DX-WKBD, that's a USB multimedia keyboard.
It has 104 keys not counting the multimedia keys.

Here's part of my rc.conf file:

LOCALE="en_US.utf8"
HARDWARECLOCK="localtime"
USEDIRECTISA="yes"
TIMEZONE="America/Chicago"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"

Here's part of my xorg.conf:

# **********************************************************************
# Core keyboard's InputDevice section
# **********************************************************************

Section "InputDevice"

    Identifier    "Keyboard1"
    Driver    "kbd"

    Option "AutoRepeat" "500 30"

    Option "XkbRules"    "xorg"
    Option "XkbModel"    "microsoft"
    Option "XkbLayout"    "us"

I left out parts I doubt are relevant.  I've also tried "XkbModel" set to "pc104" and "pc105", but still had the same problem.

If anybody can help, even if all you do is tell me where I can find some good documentation on what the "CONSOLEMAP" setting does ... and tell
me how I can tell which of the various options in /usr/share/kbd might be plausible good choices, I'd be really thankful.

Thanks!

EDIT:

I guess, if somebody could suggest a particular USB keyboard model that is KNOWN to work with particular settings, that would also be useful information, I think I can probably return my keyboard and buy a different.

Re: USB Keyboard Problem, some keys produce multiple keystrokes

i have something along the lines of the same problem.
http://bbs.archlinux.org/viewtopic.php?id=56777

my conclusion is something in the last system update screwed it up.
