yes, my KVM is a PS2 version with PS2 -> USB adaptors. From what I read, the tablet has issues with all KVMs, but you think it will work with a USB KVM?
Greg I just quickly googled on reading your original post and found quite a few response's where it worked with a USB switch , I cant say for sure as I dont have one but it seems many have it working with a USB switch .
Greg:- are you using the switch to move from your mouse to the tablet?
I have my tablet and mouse plugged into two different usb ports and both work at the same time no need for a switch.
Greg - I have my Wacom tablet on a USB KVM and it works seamlessly. I use the pen and tablet from all three of my PC's. The trick is to load the Wacom software on all the PC's that you want to use the tablet. I'm not so sure exactly what you're doing. It sounds like you're using adapters. My suggestion would be to go to a straight USB KVM. I don't think you're going to get it to work thru adapters.
