I bought an Asus A43E laptop which comes with one USB 3.0 port. In Windows 7 it was working just fine, but after Windows 8 has been installed the USB doesnt work anymore. When I insert any flash drive windows has no reaction.

I have been trying to find a driver but I couldnt find one that fits.

I know this port works cause I am able to boot windows throw a flash drive. It might be some driver missing. You guys have any idea how can I solve this?

What exactly is working on this laptop of yours? It seems like everyday, 3 other pieces break. –  Oliver Salzburg Jun 19 '12 at 18:52

Don't install beta test software on your main computing system. Report all bugs back to Microsoft. It's how they learn what's not working. Probably, a driver from ASUS isn't compatible with Win8. –  Fiasco Labs Jun 19 '12 at 19:14

USB 3.0 resides on a separate controller, and it needs a driver. You should check with the vendor of the laptop to see if there's a Windows 8 compatible driver out for this yet.

I had the exact problem as OP. I upgraded my Windows 7 to Windows 8 about 2 weeks ago, and suddenly ALL 8 of my USBs did not work.

I had MS Answerdesk perform diagnostics TWICE to try and fix it, the last time they said their level 2 agents had to work on the computer (but never called).

After searching online for the last 2 WEEKS, and finding no definitive answers as to actually fix this problem, I had to do one thing first: download AI Charger.

I was going to install and uninstall the program to see if it did anything, since AI Charger didn't show up on the populated programs list.

There were 3 options after I unzipped and loaded setup. Repair, Install and The bottom option was "REMOVE". I chose remove, as I didn't even know the program was on my computer (didn't show up on the populated programs list) and it forced a restart.

After restart: all of my USBs were working.

All USB 3.0 drivers required for your flash drive to work should be inbox in Windows 8. Can you try two things:

  1. Look for a firmware update for the USB 3.0 controller on the OEM (Asus) website.
  2. Move to Windows 8 Release Preview if you are currently running Developer Preview or Consumer Preview.

I had the exact same problem too. But, thanks to asus team for submitting their updates to windows update. I performed complete

windows update.

Now, I have USB 3.0 & Bluetooth 3.0 working like a charm.
