That is a fine question. My computers are built for me,
interestingly enough by a former IBM staffer who now works for amd. I
am embarrassed to say
that I did not ask once I started using my USB ports in DOS.
what motivated my question was my thinking, perhaps wrongly, that
there would be a bios setting for USB hardware ports the way there is
/ was for other things.
We had to worry about COM ports, back in the XT/AT days, but I don't
recall seeing them in years. Even in the DOS days, developers wrote
their own drivers, because the BIOS & DOS ones were so bad. We also had
to worry about IRQ lines back then because of the stupid way IBM used them.
I just checked my ThinkPad and the only items about USB are for enabling
UEFI support and USB charging.
