H.T.F.C.

Sorry for being so ignorant... Even as I had sent my previous post I thought
to check the Device Manager, etc, (just as you replied) in order to compare
to a similar machine, and there I found the info. Nevertheless, thanks for
your direction. with the GX280 hanging, it took some time/effort to review
as you suggested, and I hope I can relay it to you in a sensible manner, but
what I find does not appear in my limited understanding to be too unusual:

Universal Serial Bus controllers: Self-powered; 500 mA per port; 4 ports
available
-Intel(R) 82801FB/FBM USB Universal Host Controller - 2658 @ 20% Bandwidth
-Intel(R) 82801FB/FBM USB Universal Host Controller - 2659 @ 23% Bandwidth
-Intel(R) 82801FB/FBM USB Universal Host Controller - 265A @ 10% Bandwidth
-Intel(R) 82801FB/FBM USB Universal Host Controller - 265B @ 10% Bandwidth
-Intel(R) 82801FB/FBM USB2 Universal Host Controller - 265C @ 10% Bandwidth
-USB Root Hub (w/2 ports available @ 0 mA)
-USB Root Hub (w/2 ports available @ 0 mA)
-USB Root Hub (HID-compliant mouse @ 100 mA and 1 port available)
-USB Root Hub (HID-compliant mouse @ 100 mA and 1 port available)
-USB Root Hub (Generic USB Hub w/8 ports available @ 0 mA)

As compared with my other similar PC (GX520) it is only marginally greater
on the first listed controller (20% on the GX280 vs. 10% on the GX520). One
odd thing was that the second-to-last controller on the GX280 lists an
HID-compliant mouse (a second time) @ 100 mA vs. an HID-compliant keyboard @
70 mA as shown on the GX520.

Does the above make any sense to you? Can you determine if that indicates
some possible problem with the USB controllers &/or keyboard?
