Questo è quanto un user ha scritto su XDA..ora non ho il cavo usb per provare...però domani provvedo...

(Per chi non conosce l'inglese...lo impari che siamo nel 2012 :P)
OK guys i have some good news.
First of all IMO It has 100% nothing to do with hardware, so calm down.
The problem seems in a software bug.
I had the same problem whole morning today, and just now managed to fix it . First of all i tried to clean my usb hole with a toothpick, There was PLENTY of dusts and grease!!!! (Have to warn you it is a risky procedure)
After message appeared again i realized that it had nothing to do with dirty usb port.
Second thing i did , i plugged usb cable to computer,
on a phone went to USB Computer Connection -> changed it from MTP Media device to CAMERA PTP (waited for few seconds for PC to find drivers , typically pc didn't find a correct drivers so i unplugged it )
Then plugged it to pc , changed it back to MTP Media Device. Unplugged & TADA !!!!! problem was sorted. SO FAR NO MESSAGE APPEARS
What might cause a problem ?? Recently i installed bunch of apps it might be something to do with it:
Shot Control, Wifi Manager, ClockQ Pro, Remote Desktop, Thumb Keyboard, Arms and Legs, Copilot Live EU Full, Alarm Clock Ultra, Lucky patcher, SuperSU
Version: IC 4.0.3
Baseband: i9100XXLPQ
Kernel: 3.0.15-i9100xxlpq-cl223505se.infra@sep-94#3
Build Number: IML74k.xxlpq
Do hope it helps for you
