Hello Arun,thanks for your question. I assume you are following our guide to enable USB 3.1 device mode on the Agilex™ 5 HPS for the Agilex™ 5 E-series premium devkit. Please note that this guide only started working in Quartus® Prime 25.1.1; not 25.1.USB 3.1 Gen-1 Controller Tutorial Example Design User GuideHow can you tell that the Agilex™ 5 devkit is detected as USB 2.0? I checked the device using USBTreeView and it enumerated as USB 3.2 Gen 1 (which, confusingly, is basically the same thing as USB 3.1 Gen 1 and USB 3.0). Are you sure the upstream port you connected to supports USB 3.1?&nbsp;

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.&nbsp;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.PNY DUO LINK V3 USB 3.2 Gen 2 Dual Flash Drive&nbsp;I've attached the logs I see when I attach this USB Stick:root@agilex5e:~# dmesg | grep USB

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 Team&nbsp;&nbsp;I’ve updated our log, node, and kernel&nbsp; config files below. Please let us know if we’re missing anythingwe are using&nbsp;HP x796w USB 3.2 Flash Drive-Pendrive&nbsp;Striff USB to Type C Connector&nbsp;
