6.4 Network Information
The USBIP Admin Utility application enables the virtualization of USB devices over LAN as if they
are connected local to your PC. By this implementation, USB devices connected to NetUSB-400i
USB server can be made available to remote clients over LAN.
6.4.1 Function principle
This is achieved by
• Converting USB incoming Traffic from the USB Device into Ethernet Packets and transmit-
ting them to the Network and vice-versa.
• Client PCs run a client Software which makes these Networked USB Devices as USB Devices
which are connected physically to the PC.
The PC client software for USB Server consists of the following Components:
• Virtual Bus Enumerator Driver
This Driver enumerates and loads Virtual USB Bus Drivers of each NetUSB-400i USB Server
available on the Network.
• Virtual USB Bus Driver
This Driver enumerates and loads USB client Drivers on top of it. USB client Drivers then
send all requests to this Bus Driver which in turn encapsulate the requests and sends them
to the USB Server in the form of USBIP RFC packets. Once a response is received from the
Server, it completes the USB requests of the client Driver.
• Server Manager & Device Mapping of USBIP Admin Utility
Server Manager lists out all the NetUSB-400i USB Servers on Network
Device Mapping also displays available Servers on Network along with USB Devices connected
to each Server. It allows the user to connect or disconnect the remote USB Devices available
on Network.
