Are there any that are better? I have several machines here that I will
be using as embedded systems. They have one Ethernet interface each,
and I need some of them to have two. The only other non-USB ports
on these machines are video and CompactFlash.

I've thought about using VLAN tagging and VLAN switch to double up
the Ethernet port, but this is quite expensive. So, I need the best USB
Ethernet I can get.

I chose the AX88772A because it seems to be a better solution than the
Davicom DM9601 (which is USB 1.0 only). The AX88178 has more buffer
space, but I am having trouble finding reasonably priced adapters that
use it.
