There is no traffic handled while at the command prompt. It behaves
just like any other 'normal' network adapter.
So, it brings up a USB connection once you start a network action like
a ping or tftp command. Once that completes the link is brought down
again.

Within the series you can see that it was created for the Atmel
at91sam9261-ek kit.

Kind regards,

Remy
