Socoder -> On Topic -> USB Info Reader Thing...

 		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)

 		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.

 		Avtually, I spose that's what I'm going to have to do, make it myself... ah well. Cheers, I must have missed that.
