Technically, you could, but you don't want to stomp on other vendor's feet. It's a bit like mac addresses or IP addresses, you can do what you want but you probably want to behave in society (in the case of IP addresses, you'll need friends for routing). And also, to find the device from the OS API, you sometimes have to submit the VID/PID of the device you are looking for. Example: http://developer.chrome.com/apps/usb.html#method-findDevices http://developer.chrome.com/apps/usb.html#method-findDevices So changing it on the fly might be a problem (not sure, maybe once open they won't seek it again).
