I don't think regular 8.1 had it because one of the big deals of 8.5 IIRC was added USB support.
You probably can copy the extensions from iMac 8.1 or use the restore media, but a question is whether or not those extensions support generic USB cards correctly and whether or not. I don't know if that's been tested, but the absolute worst thing that'll happen is "nothing" or I suppose "the machine crashes"
