TB,
It does not matter how Device Manger is opened.
You might want to read *all* of the articles mentioned here.
[[In Device Manager, USB game controllers are listed under Human Interface
devices (in Devices by type view). If the controller does not appear in
Device Manager, then USB may not be enabled in BIOS or EFI When you are
prompted as you start your computer, enter BIOS or EFI setup, and enable
USB.
• If USB is enabled in BIOS or EFI but the USB host controller does not
appear in Device Manager (under Universal Serial Bus controllers), or a
yellow warning icon appears next to the host controller name, then the
version of BIOS or EFI may be outdated. Contact the maker or vendor for your
computer and obtain the current version of BIOS or EFI.
• If the controller appears in Device Manager, right-click the controller
name and then click Properties. Problems and suggested actions are displayed
under Device status.
USB ports have a separate entry in Device Manager. To check the device
status, click Universal Serial Bus controllers, right-click USB Root Hub,
and then click Properties. If you do not see USB Root Hub, you might not
have a USB port installed on your computer. ]]

Do you have an Intel Itanium-based computer?
[[This behavior occurs because Intel Itanium-based computers do not support
any power management features on an OPTi root hub. ]]

I recently had my BIOS and MB drivers updated by a professional.
What does this professional that you presumably paid have to say about this?

Thank you for the response. I see the same thing I do when I go in
through the Control Panel... no root hubs. They are not displayed.
There is no power management tab.

something, however, (servicing a call, for example), the operating

devices must stay on at all times. If you need the device to stay on at
all times, do not check this box.]]
The USB Root Hub should not be Hidden.

I cannot get the Device Manager to display the tab for Power Management
and thus cannot see the USB Root Hubs.
I'd like to uncheck the box "allow the computer to turn off the device
to save power".
I have set the View to display hidden devices.
I recently had my BIOS and MB drivers updated by a professional.
I have purchased three CH Products for flying (Combatstick, ProThrottle,
and Pedals) and the computer keeps dropping my stick after a while. I
have changed USB ports and do not use the ports on the motherboard as
there is a known conflict with Via chips and CH Products (the reason for
the Belkin PCI card - NEC chipsets).
I have even sent the stick back to CH, who tell me it is working
correctly.
Any help would be appreciated.
