unbinding PCI device at boot

Hi all,

I would like to unbind some PCI devices at boot time to avoid shared IRQ problems with PCI passthrough. One way of doing it is to simply write an init.d script (done that before) which is quite simple.

But before I do this, is there another better 'linux' way to do this? In this particular case it is about unbinding some USB PCI devices.

Cheers
Erik
