    Lost USB 3.0?

    My HP laptop has 2 each USB 2 and USB 3 ports. Every so often when I start up, there will be no recognition of the USB ports at all. I tried reinstalling the USB root hub and host controller drivers, but that doesn't seem to fix it. Only rebooting will get them back.

    I'm not showing any updates available either from HP or Windows Update. What could be causing this and how can I resolve it "permanently?"

    Regards,
    Chuck Billow

    What's the make/model of your laptop....the exact model #. There might be updated drivers for your firmware/hardware but on the component vendors website. You might have to go that route for the latest driver updates. I'd start with the Chipset driver and then see if there is a BIOS update for you laptop.

    It's an HP dv7. I'm not showing any driver updates needed.

    I mean the extension after the HP dv7....something like this...HP dv7-1245dx. Just the generic dv7 means nothing as HP has 40 or more different models of this line. You can find it on the bottom of the laptop or press the Fn key + esc.

    Did you try the Fn key + Esc key to pull up HP system information. Did you look on the bottom of the laptop for the model and serial numbers...they all have them?

    OK, probably because I am not running the factory installed O/S [w7 Home Premium], but instead have W7 - Ultimate, the key combos didn't work.

    I didn't find what I needed on the store order sheet either. Nor on the bottom of the laptop -- just that it was made in China.

    However, inside the battery compartment it had dv7-6C95dx.

    That's what I needed?

    Regards,
    Chuck

    Nice job....that's what I needed. I see you said your running W7 Ultimate...32 or 64 bit?

    Now if you can confirm what driver versions you have versus what is listed here......

    You do good work, BF! I'd been stumbling around looking for just this process(es) for what seems an eternity. Now we'll see if This will fix the issue. It also gave me audio drivers that may correct my Hi Def 2.1 audio as well!
