Schematic
Typical connection of USB-Host-Connector
Place 15K pull-downs near USB-connector.
For best compatibility with all modules, mount R24 and R29.
For a cheap solution, where overcurrent-detection is not needed - i.e. when using on-board USB-devices - U10 may be ommited. Though the Trizeps has a weak pull-up on USB_OC1 and USB_OC2 pins, an extra pull-up is recommended. Note that those pull-ups need to be connected to +3,3V and not +5V!
