Have you checked the USB Configuration setup in the BIOS ?
(Section 4.4.6 of the manual.) A poster in Google claims
his defaults to enabling four ports, so at least have a look
in that setup and see if everything there makes sense.
For the conflicted Root Hubs, is there any additional info
in the Device Manager for them ?
The four devices 24D2,24D4,24D7,24DE are USB 1.1 controllers.
There is a controller for every two USB ports. For example,
one controller feeds the two ports on the USB56 header, and
one controller feeds the two ports on the USB78 header. The
USB2.0 controller handles all the ports that are running at
USB2 rates at the moment. The reason for this, is the USB2.0
controller could talk to the PCI bus at 60MB/sec theoretically,
so you really cannot afford to have more than one of these USB2.0
controllers. So, the five entries for the controllers make
sense, and suggest all controllers are enabled.
I'm told that the Root Hubs normally show up when a device is
plugged in. But, as they are conflicted, you'll have to trace
further and see if there is an error reported for them or not.
I'd recommend usbman.com as a reference web site, but the
site is misbehaving right now.
As for your PDC20378 problems, I'm at a loss as to what to
suggest next, that would be likely to work. I have fooled with
the AGP slot on my P4C800-E, and I can change it from operating
in AGP mode, to operating in PCI mode, and back again. That is
necessary some times, to get AGP drivers to install properly.
I think that involved playing with the .inf file in the
driver folder, but I don't remember the details now.
HTH,
