USB peripherals work, but storage does not!

Hi guys,

 

Got a brand new build working. GA-H55m-UD2H with i5-760. everything is working fine - audio, video card, etc,.

 

However, after a few boots the USB ports become funky.

 

It will work for: (wired) keyboard, (wired) mouse, usb-wireless stick, and a 8gb USB flash drive. oh, and the wireless usb connector for wireless keyboard/mouse set.

 

It will not recognize: external HDD that connects via a USB cable, either regular USB, Mini or Micro USB. Powered or not. It will not read camera, camcorder.

 

In short - mostly peripherals work, but storage does not (besides the USB stick. I pulled an Excel file, change some stuff, saved, re-open, works perfectly)

 

I tried every usb port - first test it with hardware (like a keyboard), see it work, then plug in the drive. no reaction.

 

I thought it might be a cord problem. tried with 4 different cords. no difference.

 

>>I tried the old clean extensions cache script that used to be a problem back in the Kalaway installed 10.5.2 - which the USB become inactive after a while. Didn't do any good. <<

 

Anyone got an idea? I appreciated all inputs!!
