    Having hub only on USB2 lines

      In USB3 devices, are the USB3 lines and USB2 lines completely separate ?  Can a USB3 chip work in USB3 mode with only RX/TX connected and not D+/D- ? I'm asking if it's possible to do the following:




      I know that for sure both devices will work in USB2-only mode just fine, but will the FX3 chip in such a connection work in USB3 mode also ? Or is there signaling on the USB2 lines, even in USB3 mode, that requires there be a direct connection ?
