PCI express switch handling ..

Hi All,

I have one of these PCIe switches on one of the PCIe cards that I have:

http://www.plxtech.com/products/expresslane/pex8604

I was wondering how to handle this thing, ie;

I have to PCIe devices behind this switch, which looks thus:

06:00.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba)
07:01.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba)
07:04.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba)
07:05.0 PCI bridge: PLX Technology, Inc. Device 8604 (rev ba)
09:00.0 Multimedia controller: Philips Semiconductors Device 7231 (rev aa)
0a:00.0 Multimedia controller: Philips Semiconductors Device 7231 (rev aa)

I am wondering if i need to access or address the switch specifically
to forward data specifically to one of the bridges behind the switch.
At present I can access one of the Multimedia controllers (09:00.0) ,
but it seems I can't access the other one and hence my question as to
determine whether it is something else.

Any pointer would be appreciated.

Thanks,
Manu
