I don't think that's right. Each USB device identifies what "class" of device it is, and the host device (computer) loads the appropriate driver. One such class is Human Interface Device which covers keyboards, mice, etc. If the device is of that class, then you should be able to get key messages. But there are other classes (Audio, Communications, Vendor Specific, etc.) where key messages probably aren't sent.
