Hello Hello,

Hopefully one will be able to help me. I bought an external ssd (crucial x8) i have a laptop with a USB C 3.1 Gen 2 and when i check usb controllers in device manager i only have the 3.0 usb host. look at the screen cap please . The x8 promesses up to 1050mb/sec but since windows sees my 3.1 gen 2 type c usb as a 3.0 usb im only getting half the speed .. I d like to get full speed .. any genius in the room pls ive tried many options with no success.. (going in bios , reinstalling this and that, update drivers..) I just cant get the 3.1 controllers driver to load or else plss plsss help Thank you

    Hi ,

    I'm Rodrigo, Independent Advisor and I will help you.

    Download the Intel drivers for your laptop model from the manufacturer's website. If you need any help to find it, tell the laptop model and I can help you find it.
