Poor USB (USB2, EHCI) performance (high cpu load) — at Initial Version

Description
I have a guest with that I have exported an "Hauppauge Nova-T 500 Dual DVB-T" card to. It works, but when I use the card (record a TV show), then the virtualbox uses 50% of all availiable CPU (100% of one of the two cpu:s in the system) and the recorded tv stream is not complete (low quality due to missed data).
The same system works ok when not running virtualized.
This is with the latest 2.02 release.
