OTG problem

[bidhanahdib]

Xperia u have one cool feature that it support OTG cable. After upgrading xperia u st25i into ICS 4.0.4 Build Number: 6.1.1.B.1.10 OTG cable doesn't support anymore. I have already tried with different flash drive with different size but cannot access to any of them. Is this problem can be completely eliminate? please help me.
