We use J721S2 and SDK8.4.
When we insert USB2.0 card reader and then USB driver will detect USB device.
USB2.0 device will be mount to /run/media/sda1.
This is USB driver detect log:

But when we insert USB3.0 card reader and then USB driver will not detect USB device.
And no USB driver detect log.
How can we detect USB3.0 card reader or USB3.0 storage?
