Created attachment 1023597 [details] possible fix for KVM spew Can you try the attached patch? I don't see a HID Quirk for this KVM switch and other KVM switches seem to have this.
I don't see anymore of those messages storming the log files so it seems okay. Need to include this in mainstream now ;)
