I am working on a PCB Design and I need one USB power supply and data. I have read about CC1/CC2 configurations but I'm not sure that putting 5.1 kOhm resistors on CC1 and CC2 will work fine. I have seen one PCB Design like my design, but the designer uses two usb ports:
Why doesn't he connect USB2_N and USB2_P directly on DP1, DN1, DP2, DN2?
The designer tells to me this:
"sure you can do that, just means that you may need an adapter if you want to attach a USB device because you are also powering the board through the same connector. You also need a mechanism to detect the device role which means an extra IC to switch between the host and device role."
Thank you so much.
