ZynqMp USB Stadalone Driver with ZCU102 does not work as USB3.0

[rani.feldman]

I am using http://www.wiki.xilinx.com/ZynqMp+USB+Stadalone+Driver.

I want to evalute the USB3.0 device regarding performance and the access from Windows drivers.

When I connect the port to the PC the USB device identifies as USB2.0 and not as USB3.0

I see in the code that super speed is been configured but in the initialization phase the value read from XUSBPSU_DSTS register is always XUSBPSU_DCFG_HIGHSPEED.

Hi Yoichi,

I am using production ZCU102 kit, so I should not have this issue.

Hi @rani.feldman 

This AR has the following description.

http://www.whizzsystems.com/usb3-micro-b-plug-adapter

This adapter is shipped with production ZCU102 kits.

Customers should also always use the Targus ACH124 USB hub shipped with the kit.

Did you use that?

Thanks

Yoichi

Hi Yoichi,

We used the PetaLinux example and still we saw that the EVB is discovered as USB2.0.

But we replaced the cable we a diffrent cable and now we see that it is identifed as USB3.1 and we get USB 3.1 performance

Thank you
