Camera:Feature not supported Sony Ericsson Vivaz u8i

SOURCE: Sony Ericsson media manager software

What OS are you running? Does your system use USB 1.1 or USB 2.0? Try powering off your w910, wait a few seconds to make sure it completely cycles off, then connect your phone to your PC. It should turn on in USB (ie. 'Mass Storage') mode. If Windows attempts to Autoplay the device, Cancel the dialog. If Windows attempts to install any drivers for the device (or Vista prompts you to scan the device), Cancel the dialog(s). If you go into 'My Computer', is your phone recognized here (as a USB Mass Storage Device)? If not, the app is not going to recognize it either. Try disconnecting any other USB devices or memory card readers.
