VID and PID Table

USB uses two numbers to identify a device and find the correct drivers. The first is the VID (Vendor ID),
assigned by the USB Implementers Forum. The Newland vendor ID (VID) is 1EAB (hex). The second is the
PID (Product ID). A range of PIDs is used for each Newland product sub family, so each PID contains a base
number and an interface type (keyboard, COM port, etc.).
