Hello.
I’m having an issue that when using our customize carrier board,I was using a usbhub in the customize carrier board,sometimes it can work,but sometimes it doesn’t seem to work.
my kernel version is 4.4.38
Whenever it doesn’t work, I plug USB flash disk in, the console outputs the following errors
