I took Windows 10 off of my HP laptop and tried Windows XP and Windows 7. Both OS's don't recognize USB drives. Why is this?

Is it possible that the hardware is too new to support the drivers for older software, or could it be a problem with the computer?

I noticed this problem after stopping use of the computer for several months, and then installing the Windows XP OS.

Thank you all in advance.
