We are using two USB gadgets to allow communication over USB.
- Abstract Control Model (ACM) USB Gadget: Simulates a serial port on the host PC side.
- Ethernet Control Model (ECM) USB Gadget: Simulates an ethernet connection on the host PC side. Each CyDAQ is configured to have the static ip `169.254.7.2`. In other words, when the CyDAQ is plugged into a PC, you can ping, ssh, etc to that ip.
