3.2.3 Device Mode – Self Powered

When the TUSB2E11EVM is connected to an eUSB2 SoC that is in device mode, it should not supply 5 V VBUS on its USB connector. The TUSB2E11EVM can be powered from the USB connector or it can be self powered. If it is self powered, the jumper on J12 should be removed. A 5 V source should be connected to J11 or through a bench supply to pin 2 of J12. The J1 jumper should be removed from pins 1 and 2.
