In short, if software attempted to detect the KeyCarbon USB, it would generate false alarms on almost every keyboard in existance. The device shows up in Windows “Device Manager” as a generic USB hub. This generic USB hub has no ID strings, and is indistinguishable from the generic USB hub found in 90% of all USB hubs, 90% of all Macintosh USB keyboards, and 30% of all IBM-PC keyboards. If any software (such as a virus scanner) attempted to detect this generic USB hub, it would also flag warnings on 90% of USB hubs, 90% of all Macintosh USB keyboards, and 30% of all IBM-PC keyboards. In short, there is no way to detect the device via software, without generating false alarms on almost all keyboards.
