That indicates you have a problem with 5 USB root hubs.
That is NOT normal.
Each Root hub is usually either for two USB 1.1 ports, or more than two USB 2.0 (enhanced) ports.
All USB 2.0 controllers also support USB 1.1, so there are entries for both.

What else can you tell us?

Were your USB ports working fine previously and now they don't?

Have you experienced a power failure event since the USB ports last worked?

Have there been any lightning strikes in your area since the USB ports last worked?

Has your power supply failed and you replaced it since the USB ports last worked?

Did you plug anything into USB ports that might have caused a short?
......

Did you just connect something to a header on the mboard?

Some mboards have identical headers on the mboard for a pair of USB ports, or a firewire port. The color of the plastic below the pins is usually a specific color for each purpose. If you connect USB port wiring to the firewire header, or firewire port wiring to a USB header, nothing happens when nothing is plugged into the mis-wired port, BUT when you DO plug something into the mis-wired port, all HEXX breaks loose and you can damage whatever you plugged in, and the firewire or the USB circuits, in a very short time, and possibly the mboard as well !

CONFIRMED to be the case for your mboard !.

According to the specs, your computer came with XP MCE 2005 on it.
Did you try to load MCE on your computer using the regular OEM two CD set?
If you did, there are bugs in it's Setup that were in the first version (MCE 2002) that have never been fixed in newer versions, such as MCE 2005, the currently available version.

When you get through about 2/3 of the way loading files from the first CD and setting up Windows, it asks you to insert another CD, but the title of it is WRONG. Insert the second CD at that point. It will load files from the second CD for a while, then it asks you to insert another CD, but the title of it is ALSO WRONG. Insert the first CD at that point, and Setup will finish successfully.

If you get confused about what CD Setup is asking for and Skip loading files from the second CD, or Skip loading files from the first CD the second time, MCE is not installed properly!! You must start Setup over again, from scratch, and do it the right way!
.......

Go into your mboard's bios Setup and make sure the USB controllers are enabled.

Download the main chipset drivers from here and install them:

If that doesn't help, your mboard is damaged.

Have you installed the motherboard drivers?

I formatted my PC and loaded whatever drivers Windows calls for for my HP Pavilion a1606n, including the Realtek Audio. I still have the 5 root hubs showing in yellow.
So far, I am unable to obtain audio nor my printer.

Please answer the questions I asked in response 1 !!
......

Go to the link in response 1 for
Motherboard Specifications, P5LP-LE (Leucite3)

Make sure you DO NOT have USB port wiring hooked up to the RED header !
....

Go into your mboard's bios Setup and load bios defaults, or better still, load optimized bios defaults if that's listed, save settings.
Then go into your mboard's bios Setup again, and make sure the USB controllers are enabled (they should be by default).

NOTE: If you can't get into the bios with a USB keyboard, use a PS/2 keyboard - that should always work.


If you then still have 5 root hubs with the yellow exclamation marks, I have never seen or heard of that for any mboard that was not damaged, after installing or re-installing Windows, even before the main chipset drivers have been loaded.


When Setup has finished, you always have the support for USB 1.x already installed by Setup for the operating system.
USB 2.0 controllers have support for both USB 1.1 and USB 2.0 for all USB ports, but support for USB 2.0 is not installed in Windows until AFTER the main chipset drivers have been installed, but ONLY if the XP CD you used has SP1 or later updates built into it. If the XP CD does NOT have SP1 or later updates built into it, you have to install at least SP1 updates in Windows in order for the operating system to support USB 2.0 (when you install Windows from scratch, SP3 updates are the only SP updates Automatic Updates or manual Microsoft Windows Update wants you to install).
When you install drivers after Setup has finished, you must install the main chipset drivers.
That's listed as
Fall 2006 Original Intel Chipset Drivers
on the software downloads page for your model,
OR - you can load the latest available main chipset drivers I provided the link to at the end of response 1.


NOTE that I am assuming
- you DO NOT have an additional removable USB controller card installed in a mboard slot.
(If you DO, you should have some Root Hub listings that are fine, and you need to install the proper drivers for the USB controller card.)
- you did NOT install Windows MCE from a OEM two CD set
(If you DID, see the info in response 1 - MCE will NOT install correctly unless you insert the second CD and then the first CD at the proper times.)

If you then still have 5 root hubs with the yellow exclamation marks, assuming you DO NOT have an additional removable USB controller card installed in a mboard slot, then the only thing that can cause that is at the very least the USB controllers on the mboard are damaged - the mboard may have other damage as well.
In that case, you could try disabling the USB controllers in the mboard's bios Setup, and buying and installing an inexpensive PCI USB 2.0 controller card you install in a PCI slot, and connect your USB devices to that. However, you may then not be able to get into the bios with a USB keyboard (you'd have to use a PS/2 keyboard)
NOTE that you should NOT install any PCI card in the last PCI slot on the end closest to the middle of the mboard, unless it's a PCI video card - that slot is forced to share it's IRQ with the video, and that usually causes problems with any PCI card except aPCI video card.

You must load everthing listed in the software downloads for your model on the HP site Windows does not have the built in drivers for (except the bios update) especially the the main chipset drivers.

"So far, I am unable to obtain audio nor my printer."

You have to install the software for your printer separately. If it's connected by USB, the USB must be working properly, and usually you DO NOT plug in the printer's USB cable until AFTER you have installed the software for the printer, although, you are often required to plug in the USB cable after SOME of the software has been installed.

" I am unable to obtain audio ..."

If you have loaded the audio software from the HP site, you have probably loaded it the WRONG way. That's very common.

Audio "drivers" software almost always has associated programs that are required to be installed properly included.

You DO NOT install audio drivers while Windows is booting, when it finds an audio device, you have it search for drivers, it doesn't find them, and it asks for the location of where the drivers are - if you point Windows to where the drivers are at that point, the software almost always will NOT install properly. CANCEL that, let the desktop load, then install the audio software by using the proper software installation program.

If you DID install audio drivers while Windows was booting, go to Control Panel - Add/Remove Programs, and un-install all listings for the sound software, BEFORE you install the software the right way.
