Raberry pi 4b - USB 3.0 issues

Start by reproducing the enumeration shown by lsusb -t on the Raspberry Pi 4B, then compare the reported kernel and firmware versions from uname -a, vcgencmd version, and rpi-update. Investigate why the listed USB 3.0 devices appear on Bus 01 at 480M instead of Bus 02 at 5000M. Done means the devices enumerate at USB 3.0 speed under the stated setup, or the issue is narrowed to a documented hardware or compatibility limitation.

All (i own three usb 3.0 devices) - USB 3.0 devices connected to USB3.0 rasberry pi ports are detected as USB 2.0

i have 2 USB 3.0 devices connected to USB 3.0 ports of rasberry pi 4b. Both of them all detected as USB 2.0
pi@raspberrypi:~ $ lsusb -t

The main issue is that i switch to nvme enclosure with disk with my rootfs and want to use higher USB 3.0 speed. Check the cables, power soruces, power limitation per USB Ports. This is not the bottle neck.
