Mouse problems with KVM switch

[Mattias Björk]

Hi,

I have just brought this KVM switch:
http://www.level1.com/products3.php?sklop=20&id=590430

But Im having major problems with getting the mouse to work under 
FreeBSD. Even the keyboard does not work sometimes. This KVM switch has 
support for hotkey and also supports emulation on both mouse and keyboard.

When I boot up my system and see the BIOS on the computer the keyboard 
works just fine. Then when it continues to boot and comes to the loader, 
it still works. And the it starts to load the kernel. But then when i 
get to the login prompt the keyboard does not work.

And sometimes even thought I stay with the computer the hole boot 
process I can't even use the keyboard. So I have to use ssh to login to 
the computer and make it reboot to regain the keyboard. I have also 
tried to change the cables but I get the same results. And It works with 
no problems under Windows XP Pro.

The system that im using is FreeBSD 5.2.1-p9, at least on this system.

I  have also two other computers that Im running FreeBSD-stable on. On 
one of my FreeBSD-stable machines I have hade a working mouse under X 
Windows System (Xorg latest from ports).

But then I rebooted the system and when I started xdm, it found the 
mouse but when I move it around It didn't move like it should. It took 
some seconds before it moved and it did not move like it should, jumps 
several ramdom cm/inches on the screen (Perhaps in the direction that I 
move the mouse im not sure). Its on usable in other words.

I have also tryied to use moused under FreeBSD but I get the same 
fault/problem. I also have a problem if I do not have this machine 
selected when I boot. Then when I switch to it when the boot of the 
FreeBSD system has complete, The screen on the monitor just blinks.

Still the keyboard works because I can press two times Left Ctrl and 
then 1 to 4 to change the computer Im controlling. This I can not do 
with the FreeBSD 5.2.1-p9 system I can only see the screen but have to 
change the computer im controlling by pressing the button on the switch box.

I have tried to remove the cables and put them back again. But that does 
not help, the only solution I can see is to reboot the system and let it 
boot with it selected. I have also booted up with the mouse directly 
connected to the computer. Then when the system boot was completed I 
moved the mouse around to see that it did work. After that I plugged 
back the cable from the switch in to the computers mouse port. And the 
plugged the mouse back in the switch box, that did not work either.

I have also added flags to both psm0 and atkbd in my kernel config:

# atkbdc0 controls both the keyboard and the PS/2 mouse
device          atkbdc0 at isa? port IO_KBD
device          atkbd0  at atkbdc? irq 1 flags 0x0
device          psm0    at atkbdc? irq 12 flags 0x0

I have also tried with the flags set to 0x100 on both atkbd0 and psm0, 
but that doesn't seem to make any diffrance. I have done this on my 
FreeBSD 5.2.1-p9 box as well. I have also changed it in:

/boot/device.hints

But I don't get it working correctly either by that.

Does anybody have a clue or have hade any similar problems and/or who 
could shine some light on this problem?
