6.20 USB host
The STM32MP157x-EV1 board provides 4 USB host port (2 dual USB Type A connectors MB1262/CN18 and
CN20) thanks to a USB hub USB2514B-AEZC. The USB2514B have a full power management for each USB
host port. The default configuration of USB2514B is done in HW, thus I2C is not needed by default. However, if
required for a specification application, I2C may be accessed through MB1262/SB71 and SB68 to I2C2 as
described in Table 29.
