USB over Ethernet can be done in software.
This unit only gives you two USB ports at 100mbps? Fine for a single purpose like a scanner, not so good for anything else.
USB2 goes at aroundabouts 480mbps, perhaps they should have opted for Gigabit ethernet.
Its cheap I suppose.
But this can already be done in software without buying more cable clutter-
Costs aroundabouts £50. The advantages are that you can use somebodys existing PC, or even a server. Use a system with a Gigabit net adapter plus 6 or more USB ports, Id opt for this instead.
I've heard its very good.
