I've been looking around on the internet to see if someone has made a circuit that can read the USB VID and PID of a device, when it is plugged in, without the need of a computer. I'm working towards something that you could plug a USB mouse into, it would be able to read the USB VID and PID and then using a small database of common values, the circuit would be able to tell you that it was a USB mouse on a small LCD, or something. Does anyone know if this is possible/know a project which has done this, (even if its for firewire/some other interface/port (Ethernet would be useful))? Thanks in advance... (sorry its obscure) -=-=- ''It works, but I'm not sure why it works...'' |

I don't know how you would do the circuit parts, but the wikipedia page on USB does have a bit of info on the "USB device enumeration process" and the bit on Device Classes may be a useful reference later on.
