开发板上引出的USB 3.0 ，USB 2.0以及 USB TYPE-C接口，都是通过USB HUB(USB 5734)模块与Kirin960 的USB控制器连接并实现复用。具体连接方式如下
Kirin960-HiKey960开发板15.jpg

注意：USB TYPE-C ,USB 2.0以及USB 3.0 是通过SWITCH来进行切换的，所以如果同时使用USB TYPE-C ,USB 2.0 以及 USB 3.0接口的话，会导致其中USB 3.0和USB 2.0接口失效，这个硬件设计上的原因，使用时需要注意这一点。

when the usb otg cable plugged out, it shows the "Unable to write to file '/config/usb_gadget/g1/UDC'" message infinitely on the kernel console side.

one workaround is to stop adbd, but need to echo "none" >/config/usb_gadget/g1/UDC to start adbd again without reboot
