View Full Version : Win 8 upgrade - complete loss of all USB drivers

07-03-2013, 11:27 AM

I tried/part succeeded in upgrading my CG850 to Win 8.

But after/during upgrade I lost all access to the USB ports. Only way I can access system is using "teamviewer".
I updated all drivers from ASUS support site.. but to no avail !

Anyone else having problem upgrading to Win 8 on CG8580 ?

Are there USB drivers I can download from some where ?

Trying to right click on drivers that are installed tells me they are valid but there is explanation mark against each one ?
Furthermore there are not enough USB port listed ( only about 8 ) where as I have well over 15.

Had no issues on Win 7 Home Premium.

Any advise/help appreciated ?

Hello there, Jay.

Can you post a screenshot of your Device Manager so we can see a lit of the USB controllers? Also Click the View option and select Show Hidden Devices. See if the other USB ports show up.
