USB can use interrupts, as a gander at the Hardware information thingie
in Yast will show you. Each of your controllers has an interrupt assigned.

USB knows interrupt transfers but it doesn't know interrupts in the
way we are used to. See
http://www.embeddedsys.com/subpages/resources/images/documents/InterruptsAndUSB.pdf
for a good description. USB devices *must* be polled by the host
controller, the rate of which is established at enumeration time with
limits as described in the document.
