The Ganymede1 is a PCI USB card which supports both USB 2.0 and 1.1 with data transfer rates of 1.5, 12 and 480Mbit and provides the Amiga with two USB ports. An additional USB port is available if the appropriate cable is attached to the header on the card. The Ganymede1 appears to be a rebranded card intended for the PC supplied with Amiga drivers, but this has not been confirmed. It is supported both by the Poseidon USB stack and the VFD USB stack. A G-Rex busboard may be required in order to use the card.
