USB 3.0 micro AB acting as USB 2.0

[Sarthak]

Hello,

I am using LS 1046ARDB board. When I am trying to connect a USB 3.0 device using USB 3.0 micro AB port on the board, it says its USB 2.0. However, it should be USB 3.0.

I want to use USB 3.0 but I am unable to do so. I tried changing the wire and also tried connecting different device compatible with USB 3.0 but USB 3.0 micro AB port says it 2.0.

I have checked the reference sheet, it says 3.0 but when I connect something its say its USB 2.0. I am using all the wires provided in the kit.

Can someone please guide me how I can change the behavior of USB 3.0 micro AB to USB 3.0.

Thanks in advance

Please refer to my u-boot console log, USB 3.0 device was detected successfully without any problem.

Which version LSDK are you using? Would you please provide your u-boot console log?

In your u-boot log, Mass Storage devices are recognized as USB Revision 3.0, right?
