I have it running with an USB2Eth adaptor. Unfortunately I can't remember which brand or type. Its an asixeth device in poseidon.
I have it connected to an XSurf-clockport.
Works flawlessly sind robust except that it is a bit slow but that can be credited to the 030@50 als well.
USB is working great as well at ~ 900 kb.
