Should the USB start of frame (SOF) interrupt really be enabled?

I'm trying to get a VCP going on an F107.

Is it correct that with USB on an F107 that the USB OTG interrupt should be going off every 600us or so? It seems unlikely, as that is a heck of overhead to put on a micro.

I've tried disabling that interrupt but then it [the VCP]  just doesn't work at all.

Many thanks!
