I'm an idiot.... USB works. First, I assumed I needed to use Poseidon...wrong. The card can read it on its own without an Amiga based-USB stack. However, it is not going to automatically mount it for you. The only way I found this information was by reading the docs for the Rev3 board. You need to have two pieces of software installed on your Amiga, fat95 (goes in the L: folder) and dosmount. Both can be had on Aminet.
Then, you have to manually enter a shell command "dosmount zz9000usbstorage.device fat95 mount"
The USB stick must be FAT32 formatted.
Worked the first time I tried it. I wish it was hot swap in its capabilities, but, I guess this makes it just like anything else "old computer" related in that you need to turn it off before plugging anything into it.
I think the network port works...I cannot remember, but, I have roadshow installed on this computer, which I would not have done if I didn't have working ethernet. I commented it out of my startup sequence to make the system boot faster, as it was timing out due to no ethernet cable being plugged in. I'll have to plug one in tomorrow and verify.
