Windows 10: Can I connect an USB 2.0 drive to an USB 3.0 port?

Hi,Can an USB 2.0 drive be connected to an USB 3.0 port and work correctly?Thanks in advance, and have a nice day.

:)

 

USB 3.0 transfer speed drops to 0 only on one port. USB port and external drive are NOT defective.

I have a Dell XPS 13 laptop with two USB 3.0 ports. I connect a Seagate expansion drive to the left USB port and transfer a 4GB test file. It transfers about 1GB at 150MB/s and then transfer speed drops to 0. Then it picks up again after 3-4minutes, then
drops again intermittently.

I connect the same Seagate drive to the right USB port. The same 4GB file transfers with a constant speed of approximately 150MB/s. Thus the Seagate drive is not defective. Perhaps the left USB port is defective.

I connect a Sandisk 128GB flash drive to the left USB port (that is now suspected defective). It transfers the same 4GB file with constant 130MB/s speed, no speed drops!

Each step is reproducible 10x.

I am out of my wits here.
