Integrated Power Supply Reference Design for NXP i.MX 6ULL

2.2.4

USB Ports

This design uses the processor's two USB interfaces, where the primary USB OTG1 interface connects
directly to the micro-AB port and USB OTG2 acts as a host only, connecting to a USB Hub. The
USB2517I is a 7-port USB hub that multiplexes the USB data from OTG2 and distributes the data to 5
Type-A receptacles. The block diagram shows both USB HUB and OTG interfacing with the processor.
The wiring of the USB interfaces is shown in
