|SPECS OF PC or laptop?????|
Work the problem, not ADD to it. If your USB ports suddenly stopped working, why would a BIOS update fix that? If the BIOS was fine before, why would it cause USB ports to stop working now? That doesn't happen - if a BIOS stopped working or became corrupt, nothing would work and the PC wouldn't even boot. You need to troubleshoot the problem - that being USB:
Try going into Windows Safe Mode 1st to see if USB works.
Just another stupid saying...
