I use Rosewill RNX-G1/G1W for my "USB" NIC and it has worked great, although I
only tested in on Ubuntu 10.10 and 10.04.
It was only $19.00.

Ubuntu.
Specifically a mythbuntu.
I need to retire my old file server, so I decided to go with this one.
Network "card" is DYNEX USB stick.
It is a $10 wonder which crashes quite a few modern Linux distros when plugged
in.
If I have time I'll try to do few things mentioned in the thread. Basically I
was transferring files from my office at UNO. (LinuxMint box) That is one of the
reasons the file transfer rate was topped at around 1.6MB/s.
