Hi, James.

As they used to say, "I don't understand all I know about USB." ;^]

My motherboard (EPoX 8KDA3+) came with 4 USB 2.0 ports on the back, plus two
headers for 2 more 2.0 ports each for the front and back of the case. All
those are connected now, so there are 8 2.0 ports managed by the mobo BIOS.
In addition, I added the 4-port Belkin PCI card that I had bought for my
former mobo, so I now have an even dozen USB 2.0 ports - more than I need.
As I recall, the Belkin card needed the drivers supplied with it when it was
in my old mobo.

After plugging in my new camera, I got the "non-high speed port" message.
That's when I looked in Device Manager and found the hidden USB drivers in
another category and deleted them, as I said before.

Now there are 14 lines under USB controllers in my Device Manager (and NO
hidden devices). Six lines say USB Root Hub, one is for my ATI Remote
Receiver and one for USB Mass Storage Device. That leaves two sets of 3
each. One set is "NEC PCI to USB Enhanced Host Controller (B1)", followed
by two copies of "NEC PCI to USB Open Host Controller"; the other is
"Standard Enhanced PCI to USB Host Controller", followed by two copies of
"Standard OpenHCD USB Host Controller".

The NEC Enhanced driver is from MS, dated 6/1/2002, version 5.1.2600.0;
Driver Details shows:
"File version: 5.1.2600.2180(xpsp_sp2_rtm.040803-2158)"
just like yours. But there are 5 files, including usbehci.sys and
hccoin.dll; the other 3 are the same as yours (usbhub.sys, usbport.sys and
usbui.dll). Except for the name, the "Standard Enhanced" controller says
the same things: numbers, filenames and all. Each of the 4 "Open"
controllers includes usbohci.sys, rather than usbehci, and the other 3 files
(usbhub.sys, usbport.sys and usbui.dll), just like yours.

Have you visited the website for the maker of your USB card? They may have
later drivers, or an answer in their FAQ. Also, have you expanded every
line in Device Manager to make sure no USB drivers are lurking in an
unexpected category? Like mine. Or, just delete EVERY USB driver you can
find, disconnect every USB device, then reboot at least once and let WinXP
redetect the hardware from scratch. After the hubs are detected and working
drivers installed, then plug in the devices one at a time to finish the job.

I'm about out of ideas here, so I hope somebody else jumps in with something
helpful.
