USB 3 ports do not work

fireberd: thanks for sticking with me.

I went back to the Intel site and manually downloaded the chipset. The single USB2 port still works, the three USB3 ports do not work. A change in the description appeared in the Device Manager: The (two) Standard Enhanced PCI to USB Host Controller is now called,
Intel 7 Series/C216 Chipset family USB Enhanced Host Controller - 1E26 (the second one is called 1E2D).

My Microsoft Office 2000 is the edition that would not work in WIN-8.
When I tried several months ago to install AutoCad14 on my desktop WiN-7 Home Edition, it would not do anything except refuse. I did not know at the time about Compatibility Mode. I did find out later that AutoCad14 would install in WIN-7 PRO in "XP Mode" on this new laptop. That is one of the reasons I removed WIN-8.

I was going to paste the screenshot of the Device Manager, but I don't know how. I could do it in Microsoft Word, but not here. I copied by clicking "prt sc" and then I could paste in MS Word, but not here on this forum. There are probably instructions somewhere on the forum, but I didn't take the time to look.

On the HP trouble shooting page, it suggests un-installing the "USB Root Hubs" and then restarting the PC. I did this and it automatically reinstalled them exactly like they were. I am now wondering if I need to plug in some USB3 device and then expect the PC to recognize the port. Up to this point, I have just plugged in the Logitech cordless mouse to test the different ports. Since it is an old device, maybe the USB3 port will not recognize it. The mouse does not work in any of the USB3 ports, but does work in the USB2 port.

Thanks fireberd. I will quit bothering you for now. I may go back to HP and see if they will provide USB3 drivers, even though I have mutilated their product. I do not intend to return the laptop to Fry's or reinstall WIN8. I consider it my problem since I did not do enough homework before the purchase. It works well otherwise. I do not need the USB3 port for my purposes, at least not today. Since the ports were there, I just wanted them to function. Thanks again for your help and "patience". Joe

Thanks to all, especially fireberd. I posted on the HP Forum and a guy named Paul directed me to a USB3 driver download. Now, all three USB3 ports work and even the USB2 still works. Amazing.

Here is the link in case anyone else is interested:

HP EliteBook 8570p Notebook PC - Intel USB 3.0 Driver - HP Business Support Center

The Device Manager now shows:
Intel USB 3.0 eXtensible Host Controller
Intel USB 3.0 Root Hub

These did not appear earlier, so the old man was confused when looking for USB3 ports.
Thanks again
