I assue that there is not? I can think of only one possibility, which is to prevent _all_ warning messages from showing up on the console. You can do that as follows: echo 4 >/proc/sys/kernel/printk or even simply holding down the Alt and SysRq keys while pressing 4. This won't prevent the warning messages from going into the system log, though. Of course, you could always get a different brand KVM switch. That would stop the errors.

Okay, then I was wrong about the KVM being unintelligent.

Maybe that "phantom" device refers to the pusbutton on the KVM itself.
In any case, it clearly is the case of those error messages. Below is a
patch for the USB HID driver in 2.6.18 which ought to help.

Re: [Linux-usb-users] No input interrupt endpoint
It's showing two keyboards? There is only one connected. It must be some kind of 'phantom' keyboard presented by the KVM switch.
