Hello, I have a lexar 64gb usb 3.0 drive that worked well for a year almost, reading with almost 400MB/s and writing with about 250MB/s on average.

Yesterday it just downgraded to usb2.0 speeds and reads/writes with 40MB/s .
I tried format i tested in 3 different pcs with windows with linux, no change.
Windows tells me "this device could perform faster if plugged into a usb 3.0 port" and i'm like You don't say ? I've been using it for a year i know for sure it's in a usb 3.0 port.
What can i do to make it work at usb 3.0 speeds again ? can it be a hardware problem ? I'm pretty tech savy and don't mind reflashing it's firmware it's just that i have no experience dealing with this particular type of problem.

Check Device Manager and make sure under Universal Serial Bus Controllers your USB 3.0 controllers are detected properly.

They all do. And it s a fresh win10 install too.all other usb3 devices work. Something wrong with this one's firmware ? Someone at Tom's hardware said usb3 pins could be bent so only usb2 pins connect and that's why but I don't see any bends. Just normal wear
