In respect to what? A google search gives me Pelvic Inflammatory Disease and a Russian television company.

Alright, seriously, in Geekspeak, an acronym in the form (X)ID usually refers to some identifier. Where are you reading these numbers? The values listed look like hex addresses.

(2)What I can do with them?
A good rule of thumb: If you don't know what it is, leave it alone.

VID = Vendor ID
PID = Product ID

Basically for USB device identification.

You don't do anything with them. That's how the OS identifies the hardware.

This is a good explanation.

In addition, the PID can be used by software in the host and client to verify, enable or restrict access through the USB.
