Question Slow USB 3.0 speeds on Gigabyte B550 Aorus Elite v2 board ?

Just build a new system , and i dont know if its the drivers or a conflict of the B550 motherboards ?
But every time i use the Red USB 3.2 (Gen2, 10Gb/s) ports and i want to upload something on my External SSD Samsung T7 for example.
The speeds starts at 300 MB/sec then drops all the way down to 18 MB and sometimes it stalls at 0 (Rollercoaster)even when using High speed Usb 3.1 Sandisk devices,
i don't get the speeds i used to have on my previous build with the same ext drives and usb stick.
Dont even get half what the speeds goes for on the device.

When using the Blue ports USB 3.2 (Gen1, 5Gb/s) i do get a stable steady transfer speed, but not the speeds i should have
Does Gigabyte use multiple controllers for Usb on the Aorus B550 Elite pro V2 ?

I hope you experts could shed some light on this annoying situation

Welcome to the forums, newcomer!

What BIOS version are you on for your motherboard? As for your chipset drivers, peraps try and reisntall them in an elevated command, i.e, Right click installer>Run as Administrator.

Im running Bios version F15 , i downloaded the latest available chipset drivers from Amd directly .
What do you mean with "elevated command" ?

Status Update : After updating with new chipset 5.02.19.2221 posted 28-2 and using the latest Bios F16b .
Even though not stated anything in changelog of bios, my USB 3.2 Gen 2 Speed is back as it should be.
Finally my T7 disks reach 700 MB/sec again .
Thought maybe it would be of intrest to anyone here
