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

Jump to solution

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,

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

Hello @rani.feldman 

 

This may not be the solution. This is a reference only.

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
