I just installed a no-name 5 port USB 2.0 PCI card (Intel Chipset) in
my desktop. It shows on Device Mnager as "Intel (R) 82801DB/DBM USB
2.0 Enhandced Host Conbtroller - 24CD" -- fine so far.
However, when I plug my Logitech Fusion webcam into it, the webcam
"adopts" a standard USB port - I've tried everything I can to get
this 2.0-hungry webcam to adopt the 2.0 controller, but it stays on
USB 1.
Ideas? |

Is a Standard USB Port listed separately in Windows Device Manager,
and can you disable or uninstall that so that the 2.0 Host Controller
is the only available option?

Accoding to Logitech, the webcam should show up under Root Hub under USB 2.
It dos not show up under any of the USB Root Hubs.
It shows up only under "Imaging Devices" uin the Device Manager's
"view by type" view.
Again: how do I get this webcam under USB 2? (I've installed and
reinstalled, etc..)
Tnx

You said the camera "shows up only under 'Imaging Devices'",
but I see it listed as 'Logitech USB Camera (Fusion)', under
the USB Serial Bus Controllers in the picture. Have you
r-clicked on both that and the listing under 'Imaging Devices'
to determine more about its properties?
Also, it may be listed under 'Imaging Devices' because it's
using USB 1.0. It's possible that disabling (NOT uninstalling)
all but the USB 2.0 Enhanced Host Controller under Device
Manager will force it to use 2.0. As ayub12-ga stated, you
should unplug the cam, disable the other USB listings, then
restart the computer and plug in the camera. However, you
might accomplish what you want simply by disabling the
Standard Enhanced PCI to USB Host Controller.
When you say, "It does not show up under any of the USB Root
Hubs", do you realize that you would have to r-click on each
ot the 7 root hubs listed, and check the various tabs to see
if one of them is associated with the camera? You might try
this before doing anything else.
