I recently bought a Noppoo Choc mini (and really like it). I tried to use it with a KVM and was having trouble with it. If I plug in the kb to each computer by itself, all is good. I hook up the KVM and strange things happen. The keys send different keystrokes. The "N" sends "3". Consistently. I've never heard of this. I've tried 2 different KVMs from diff manufactures same behavior.
Any ideas? Is this a common problem?

The Choc Mini is able to achieve NKRO via USB by making itself a "compound usb device" within windows. It is not a single keyboard, but instead several keyboards, and this can cause problems with some computers or setups. This is also why they don't work on Macs. (I think)
Plug it into a computer directly and take a look at device manager. You'll notice at least two input devices.

Evil Spork probably has the explanation there, but I figured I'd this ask anyhow. Are the KVMs USB or PS2? It is said that PS2 KVMs don't like having a USB keyboard plugged into them with on of those little USB to PS2 converters.

I did see two keyboard devices. I scratched my head and forgot about it. I guess that makes sense.
Thanks for the info. I guess there's nothing for it? Soon I will have no internet on my work computer, with internet on another machine (I love working for the US government). A kvm would be really nice.
I read something about using a USB hub in the kvm instead of a keyboard. Maybe I will experiment. At least I know what is happening.
Thanks again.

kvm is usb. but thanks anyway.
