Slow connection speed, similar situation to another issue from RTL88x2BU thread

[horugane]

Title, I came from Windows and was struggling to install proper drivers to my Wifi adapter until yesterday. However I found out my connection speed is abysmally slow (using Steam download speed as reference) until I found the issue thread to learn that I'm running the driver at USB 2.0:

lsusb -t: Port 004: Dev 003, If 0, Class=Vendor Specific Class, Driver=rtl8852bu, 480M

Yet, I'm plugging the adapter at USB 3.0 port and I suspect that it might be different from the case from 2 years ago so I figure I could write a new issue thread to make things clearer for my particular case.
