USB root hub Power usage tab missing

[Ian D]

Has the Power tab for USB root hubs in the Device Manager
been removed by a recent update - last couple of months or
so? The reason I ask is it's no longer there in 3 up to date
XP Pro installations, retail and OEM, but one install that's
about a dozen updates behind still has the Power tab.

This refers to the USB port power usage tabs, not the power
management tabs that are still there.

No. I have all updates and still have my Power tab and Power Management
tab.

Although I didn't see anything relating to it here, you might look anyway.
