I have installed many ROMs, and the phone worked fine.
One day (and I don't know why), Windows couldn't recognize my Huawei. Windows can't install the drivers, and it named the phone as "Unknown device". I already tried all options in "Device Manager".
I have tried using another PC, installed and reinstalled the drivers, another OS (Ubuntu), another cable, but still nothing.
USB OTG Helper made this report:
-Storage Module live
-NTFS read-write supported
-Mount: No drives found!
and USB Host Controller
-S3C USB Host driver NOT found
