Windows CDC drivers issue

Apparently I was trying to connect my Samsung Galaxy S2 I9100 to my Windows 7 system

  1. Kies installed  – nothing happened
  2. Drivers from Samsung installed – nothing happened

It kept showing that drivers for CDC were not installed

Finally got the fix from XDA developers forum

We need to switch teh UART and USB settings:

Enter UART mode with *#9090# and select "Log via UART"


enter *#7284# and select "UART MODEM" and select "USB PDA"

Now Windows ask normal Samsung drivers!
