是什么原因造成的？要怎么填坑？

你用的是 @chong 的linux4.19 补丁吗?
是的晕哥，请问需要电路上做什么改动吗？
离线
那个 4.19 我还没来得及测试.
我猜设备树 usb缺一个 dr_mode 属性
https://www.kernel.org/doc/Documentation/devicetree/bindings/usb/fsl-usb.txt
http://processors.wiki.ti.com/index.php/MUSB_Linux_Porting_Guide
- dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
controllers. Can be "host", "peripheral", or "otg". Default to
"host" if not defined for backward compatibility.
&usb1 {
status = "okay";
dr_mode = "host";
};
你按上面这样配置一下， 看看效果.

不用改动，直接打了patch就能用

貌似reboot还是会失败。。。
这该怎么整？没经验，求指教？

mainline 中是一样的做法的。不过电路异常的话，相关的看门狗设置会出现问题，目前h3就遇到了一块那样的板子。需要自己改一下重启看门狗相关的参数。
