New PC Parts but only USB2.0 Speed?

[GnB]

Hi I have a problem with my PC.. I got new parts for christmas (switching from old Intel X58 Xeon to Modern Ryzen 2600/16gb Ram& Vega64. But there is only one weird issue:
I have a USB 3.0 Drive from Intenso and when I copy files with my new rig it limits the usb speed to 2.0 meaning 30mbps transfer rate, when I plug the USB Stick into a second computer thats older with Intel I5 2500k the transfer rate is about 100mbps meaning usb 3.0 
For Troubleshooting I tried: 
Different Ports on the back and the front/io
Checking in BIOS if USB3.0 is enabled
Formating the USB Drive to ntfs or exfat 
Formating my C Drive and installing a fresh version of win11 with all driver updates
All of my solutions didn't work has anybody some ideas maybe why it is behaving in that way?
Btw, sorry for my bad englisch greetings from germany!
Specs: 
ASUS ROG B450F Gaming Motherboard
Ryzen 5 2600@Stock

16GB DDR4@3200Mhz

NVME SSD 240gb
Vega Sapphire Nitro 64

op said he tried all of them on the front and back

which motherboard ? USB 3 ports tend to be blue or red, USB 2 ports tend to be black

which case ? (probably the old case only has USB 2.0 ports, like mine)

I used all Ports with usb 3.0 or higher standard, and I have a fairly new Case from Sharkoon with USB3.0 only for front usb..

Are you transferring many small files, or one big one?
