The issue is not what interface the UPS uses, but the port(s) on your mobo.
"lspci -k" will show which kernel drivers your USB controller(s) use
You can also look at the mobo manual, or plug the model # in the
manufacturer's website, and check it's specifications.
Very doubtful you have USB 1.{0,1}, and iirc, almost, if not every, EHCI
controller has an integrated Transaction Translator so that you don't need
UHCI/OHCI anymore.
