Firstly let me say one thing, this is not a problem with ASMedia controller. I thought it was.
There is a solution and it is installing the modded Windows 7 drivers from Intel, because the Microsoft drivers included with Windows 10 are completely broken.
I had this issue for months. After installing the modded drivers, the issue is completely gone. I've been running the PC normally without USB issues for at least 6 months after installing these drivers.
They can be found on this page:

B. Latest modded Intel USB 3.0/3.1 drivers:
READ, RESEARCH AND MAKE SURE YOU DOWNLOAD THE CORRECT ONE FOR YOUR MOTHERBOARD! If you download the wrong one then don't complain it doesn't work as it is your mistake.
This is all I can say. I will not provide any further help because ASUS is not paying me.
