Need help for USB in NT

Recently I have had reason to replace the UPS on an e-series server running Mindows NT.The UPS requires a USB connection.while the Mobo has USB ports,the OS does not support USB.I know there is software and even some hardware available to remedy this,but being the first time I’ve had this sort of issue,I need some input as to what I should do.Any and all suggestions would be welcome…excepting one,I have already tried to talk my client into an upgrade and it’s still on the table,so in the meantime I need a quick (or not so quick) fix.
Thanks all.
