Device Identification USB, Ethernet etc

Hello All

How does one go about implimenting device Identification on a network or bus

You know you plug a USB printer in and it says HP1234.. or what ever and how do devices negotiate tranmission of data when other devices try to send data data at the same time.

I know thid has a specification in the OSI layer model but I need to do the same thing - what interface ICs out there which I can incorporate in to a application without programming.

I'm trying to develop something based on 1wire for machine monitoring.

thanks

USB and Ethernet both administer programs to provide unique electronic identifiers to devices from different vendors. Your chances of doing it without programming appear to be remote -- so to speak.
