USB3 devices detected as USB2 in petalinux

Hello,

I'm trying to connect a USB3 camera to the Ultrazed-EV starter kit using petalinux, and I can see that the camera is being detected but as a USB2 device, here is the shell log:

I set up the USB mode jumpers in the board as a default HOST mode indicated here: http://zedboard.org/sites/default/files/documentations/UZ-EV-CC-UG-ver1.pdf (page 12), also tried OTG configuration with same results.

In order to connect the camera to the board I'm using the next adapter:

https://www.kenable.co.uk/en/usb-cables-adapters/usb-30-superspeed/7005-kenable-usb-30-superspeed-a-female-to-micro-b-male-10-pin-adapter-007005-5055383470051.html?gclid=EAIaIQobChMI4PmPkMKO4gIVmIjVCh1dxAukEAQYASABEgJzBvD_BwE

The camera is detected and works as USB3 device with not problems in a windows or linux PC (without the above USB adapter).

I tried another devices as a USB3.0 memory stick and they are also detected as USB 2.0 device....

Any ideas what could it be the problem?

Thanks in advance.

Hi there,

While I'm looking into the configuration we used to test this, can you confirm that you set 3 jumpers to host mode?

Hi,

Thanks for the reply.
Yes, I've got the next jumper setup:
JP12      ON
JP21      pin 2-3
JP23      pin 1-2

I looked around the web and I've found some clues that it could be related to the USB3 adapter....

I'm trying a few different adapters and none are working so far still detecting the USB3 devices as USB2.

I've got a couple of questions:
1) Did you test USB3 interface successfully with an adpater with this boards? if so, could you please point me to a working one?

2) On the other hand I opened the provided 2018.2 BSP Vivado HW design and in the zynqMP processor settings the USB3 VBUS is not selected, do I need to activate this option?

Thanks.

I finally got it working.

As I suspected it was the USB adapter, I've found one that works now. It was matter to try different ones...

Thanks

This is great to know! Yes, we used an adapter, but I did not get a reply which one as of this post.
Can you please post which one you used, so as to help others?

I'm glad you were able to get this working!
