No switching, as I see it. This can't be done with a standard hub - with the exception of some special devices with "USB on-the-go" (some tablets/phones/PDAs), USB ports are either A (computer or main ports on a hub) or B (device or the "uplink" on a hub). Normally a hub only has one port which can connect to a computer. There are some "special" hubs where you can attach two cables and have a button that just disconnects from one computer and connects to another but they appear to be poorly made junk, and if you can't even find USB KVMs, there is little chance you will find these.

Those two nodes would never work at the same time. I do not need to switch at all, just to have cables set and to avoid messing with the back of computers. Usb keyboard is happy hacking lite 2, sadly does not work as PS/2. Not in any configuration. It is as it is. So, my probably stupid idea was to have 4 adapter hub, to put usb kb and usb mouse into 2 front ones and the rest adap- ters to use to connect usb cable from adapter to usb on the computer. No switching, as I see it. Monitor has dvi and d-sub adapters and I could connect two nodes, without disconnecting cables. Best regards all Zoran

The only way this could work is to switch the cables over when you want to change to the other box. If you can find a second monitor but would like to share one keyboard/mouse between the machines, you could look at net/synergy, x11/x2x or x11/x2vnc. These let you move the mouse "off the side" of one screen, and when you do that, transfer keyboard/mouse information to the other box using a network protocol.

I don't see how a plain hub could possibly work as a KVM switch, unless I am missing something. A workaround you may consider would be a PS/2 KVM switch where the KVM switch's PS/2 exit cables go into PS/2-USB adapters. (Or are those adapters just as rare in your area?) -- Shawn K. Quinn
usb hub as kvm switch
I have two nodes side by side. KVM switches for just usb are almost imposible to find in my area. I plan to use usb keyboard and usb mouse only, since my mo- nitor has two adapters for both boxen. Is it possible to use plain usb hub to do the job? One of the nodes would be openbsd 5.2 amd64. Best regards Zoran
