My experience with "mix and match" USB ports and devices caused a bit of
problems.  My external backup drive is in a USB-3 housing, and I
connected it to one of my Dell tower's USB-3 port with a USB-3-rated
cable.  I experienced quite a number of  failures to recognize the drive
at backup time. After replacing both the drive disk and housing, the
results were the  same.  When I moved the cable to one of the computer's
USB-2 port, the problem went away.

The upshot of all this is, to paraphrase an otherwise forgettable MIT
professor of many decades ago "this USB not the same as that USB - I
only did that to con-fuse you".

I'll let Don and the rest of the experts here give more accurate answers.
