According to the schematics it should be powered using the OTGVBus-Port of the Cypress-Controller (nevertheless it has currently no level) - Secondly there is no configuration 1 Host + 2 Peripherals according to the datasheet from Cypress - Thirdly the initial configuration (at least that is what we are guessing) seems to be done via some standalone program coming from an Eeprom. - The three pins near the UART port are the serial console for the Cypress chip (we have not yet done any tests with that). - At least the peripherals are connected in a right way, as one SIE can only have one peripheral Some question aside the peripheral topic: Has anyone any idea how to make the cypress chip to have a _normal_ Host not an OTG one (as some USB-Hub might save us from our dilemma why we tried to use gadgets in peripheral mode)?
