USB ports do not work

[djenkins3467]

Hello:   I have a similar problem.   Fairly new Zbook Studio G3 and 2 of the 3 USB ports do not seem to work.   The 2 on the left do not work,  the one on the right side does.   OS is W7 Pro 64 bit.  Latest windows update and drivers are I believe installed.  I dont have an unknown device in my Device Manager.  One thing that is odd is that during the installation of the Realtek USB and Media Card drivers,  specifically SP80267,  HP's support assistant cant find a windows file to do the update, so this fails to install.  I am wondering if this may be why the USB ports on the left side do not work.  Any ideas?

Hi, Dave:

For the USB ports, the only suggestion I can offer would be to try the latest USB 3 driver directly from Intel.

Download, unzip and run the setup application.

The SD card reader would have no bearing on why the 2 USB ports aren't working.

I suggest you install the latest SD card reader directly from Realtek.   Download, unzip and run the setup application from the 1st file listed on the page.

Windows names too many devices as unknown when the driver is missing, so the only way I can help you find the driver for that would be for you to post the hardware ID for the unknown device.

Use this guide for how to find the hardware ID for a device...

Ok thank you,  I will try the first 2 and see what happens.  If still stuck I will post the hardware ID's.

Thanks,  Dave
