Hi all,
I have a few computers that I control with the same keyboard, mouse and
monitor via an electronic switch. Namely a Linux PC and an Apple (macos x),
but now also a PC with openBSD. Both Linux PC and Apple work fine with the
switch, only with the PC with openBSD the mouse does not work. No problem
with the keyboard and monitor. The mouse is of the wireless type, so radio
controlled. What is the problem here, and what can I do about it?
Hi Karel,
I have a KVM switch too, though not sure if they are similar. I can control
three computers and a possible fourth if I had it hooked up. There is USB
inputs for keyboard and mouse and an extra USB port on a hub, as well as
a built in sound card that has an on/off switch. I also have a selection
button that toggles the PC # I want to switch to. This is also doable
by pressing shift-lock twice and the number 1 through 4. This is a USB
intercept and not passed through to the computer which was selected's hardware.
The way I fathom your setup is similar to mine, with an adapter for the
wireless mouse to go into USB? It is always good to post a dmesg with
any hardware description so I'm gonna ask you for yours, it also doesn't
hurt to give a usbdevs output.
Best Regards,
