Hi Murray,
Well this is a whole different beast......
A USB/Ethernet concentrator (Router)
I think it has a uproc on board and yes...
It requires drivers or at least configuration software to be
configured/installed!
And I think it's way out of our league pricewise... :-(
And yet another box.....
In my posts I was talking about USB-stick sized USB-to-Ethernet adapters and
you would also stick them just like an USB-stick into an USB port.
They need an OS/host to work and you need to install driver software on that
host.
73's,
Henry.
