Occasional ContributorHi 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?
New ContributorHi Team
I’ve updated our log, node, and kernel config files below. Please let us know if we’re missing anything
we are using

Striff USB to Type C Connector
ContributorHello 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:

New ContributorHello 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.
New ContributorHi White
I am also getting those prints print QPD25.1 But still
but while testing the version it detects as 2.0 all time
ContributorHi Arun,
There is a utility called `lsusb` that you can add to your Yocto image. Add the following IMAGE_INSTALL line to gsrd-socfpga/agilex5_dk_a5e065bb32aes1-gsrd-rootfs/conf/local.conf:
# CONF_VERSION is increased each time build/conf/ changes incompatibly and is used to
# track the version of this file when it was generated. This can safely be ignored if
# this doesn't mean anything to you.
CONF_VERSION = "2"
# support lsusb
IMAGE_INSTALL:append = " usbutils"Then rebuilt your SD card image with
bitbake gsrd-console-imageThe output I see when the PNY USB stick I linked above is plugged in:
root@agilex5dka5e065bb32aes1:~# lsusb --tree
