Another project I've been working on is a new USB controller via the ACSI port.
I have a Medusa T40, but it doesn't have a ROM port, so I couldn't use the NetUSBee, and to keep it simple, I just wanted USB, so I can write a USB->Ethernet driver too.
I have it working with the MiNT USB drivers and the usb-storage driver currently, but I'm working on ethernet support next.
* It's got ACSI through port for connecting your traditional ACSI devices, such as the UltraSatan.
* It has a jumper selectable ACSI ID.
* It only has a single USB port, the second is purely to provide 5V power to the board. So you're likely to need a USB hub anyway.
* Doesn't use the ROM port so it's free for those musicians that need their ROM port dongles.
Here's a picture of my prototype plugged into my T40.
If anyone feels interested in a unit, PM me, as currently I don't expect many people to want one. I'll probably make a case for this too.
