4.7 USB Host / Device Connections
While the Open-Q
TM
410 Development Kit provides a USB micro-B (device, J601) connector and a dual USB
Type-A (host, J602) connector, the functionality of these connectors are mutually exclusive, with the USB
micro-B connector taking priority.
NOTE:
DIP switch (S501) must be left in the OFF position. The selection for USB device or host is determined by the
connectivity of the USB micro-B connector (J601) to an external USB host. If J601 is connected, the USB port
operates as device mode. If J601 is not connected, the USB port operates as host mode on J602.
It is recommended to power down before switching the USB device / host capability.
