This paper describes a high-speed USB2.0 Address-
Event Representation (AER) interface that allows simultaneous
monitoring and sequencing of precisely timed AER data. This
low-cost (<$100), two chip, bus powered interface can achieve
sustained AER event rates of 5 megaevents per second (Meps).
Several boards can be electrically synchronized, allowing simultaneous
synchronized capture from multiple devices. It has three
AER ports, one for sequencing, one for monitoring and one for
passing through the monitored events. This paper also describes
the host software infrastructure that makes the board usable for a
heterogeneous mixture of AER devices and that allows recording
and playback of recorded data
