The OS win98se provided the ability to use USB ports on a system. But, you're wanting to match that to a 386 based PC which wasn't part of any offering when that came out. At best it may have been for 486 based PCs, but even then that was a rare duck. It came to P4 based PCs to more readily use USB. On top of all win9X based PCs still needed the flash drive that they provided in order to use the flash drive from that maker. All in all, it becomes quite difficult process to make a 386 based PC to even get use out of 386, not that it couldn't but it JUST WASN'T available back then. You may have a PC case that has USB ports but these may not be connected to anything and if they are, they're USB 1.0 or 1.1 rated. When it comes to 386 on its own, that's really drags things around and hoping for the best. The last advise I can give is hoping the install of a USB pci type card may allow such usage which in turn depending on it's make-up may have int. connections to PC case ports. I supply this advise as re-reading your original post, you gave little clue to where the USB ports are, maybe case or other area or card. of course, details would have helped here but "as is" I find this a very difficult task to complete.
