XG270HSU usb problem

theislandland

Hello!

 

Ive gotten a strange problem..

 

Usb devices are loading power, but not connecting, cellphone, mp3 player etc..

These all work on all other computers, also work if i connect them into the motherboard backside directly, but not throu the XG270HU usb ports, ive tested all 3.

 

Ive tried to reinstall windows (format and install), drivers.. same problem.

 

Now a couple of weeks ago the XG270HU usb ports worked just fine and cellphone, mp3 player loaded its storage just fine as a disk in windows 7. I have not updated anything like firmware etc..  

 

It was bought 22 of dec 2015.

 

XG270HU is connected with the DisplayPort.
