    CYUSB3KIT-003 EZ-USB FX3 using an USB storage device on J1: how to supply power ?




      Today has arrived my CYUSB3KIT-003 EZ-USB FX3 SuperSpeed Explorer Kit and I need to interface to an FPGA.

      The basic idea of the connection is the following:


      FPGA => CYUSB3KIT-003 through GPIF II => USB (2.0 or 3.0) storage device.


      Then I read into the UG (https://www.cypress.com/file/133836/download ):


      "The SuperSpeed Explorer Kit development board is powered from the USB 3.0 connector J1. This development board does not support self-powered mode, although the FX3 device does support it."


      So what is the correct way to supply power to the board in case of using a USB storage device connected to J1 ? Isn't it possible to work this way ?
