3.4 USB Connectors
The USB interfaces on EX-9686U-L include a USB 2.0 OTG port and two USB2.0 host
ports. Speed of up to 480 Mbps supported.
The USB 2.0 host interface is connected to a hub controller to extend host ports. Two of the
USB2.0 hub ports are available for users. The other two USB ports are reserved for
802.11b/g/n WiFi module and 3G (WCDMA) module.
NOTE: The USB 2.0 OTG can be used in host mode or device mode. If you would like to
use it in host mode, a separate OTG-to-host cable is required.
The USB 2.0 host connector is a regular USB type A connector that can be connected to
+5V USB storage device. This port is mainly used to connect to USB flash drive.
