Hello Team,

We are testing the USB 3.1 interface on Agilex 5 using Quartus version 25.1. All the required drivers have been enabled, but the device is still being detected as USB 2.0.

We noticed that there is a workaround mentioned for this issue in version 25.3. Could you please confirm whether this USB 3.0 detection issue is expected in Quartus 25.1?

If yes, would applying the workaround or changes introduced in 25.3 help resolve the issue in version 25.1 as well?

Hi Arun,

USB3.1 in Host mode is enabled by default in Agilex 5, including 25.1.

The workaround in USB 3.1 Gen-1 Controller Tutorial Example Design User Guide is mainly to enable the Device mode (a change from the Host mode), using 25.1.1.

May I know how you see the device being detected as USB2.0?

      Hello Arun, thanks for sharing. 

      I suspect the problem is your USB to Type C connector; those adapters can sometimes silently downgrade USB speeds. I tested using a USB mass storage device that has both a USB-A and a USB-C port, and I verified USB SS speeds using CrystalDiskMark and fio.

      I've attached the logs I see when I attach this USB Stick:

      Please note that I built this Linux image using the newer GSRD 2.0 (tested with Quartus® Prime 25.3), which uses Kas to manage Yocto layers, but the Linux configurations should be the same as the 'classic' GSRD.

        Hello Team 
        We have tested this on other iMX boards where USB 3.0 detection works as expected.Also we have validated with other pendrives we have still it detects as 2.0 Now I need to validate USB host mass storage  on QPD25.1.
