Symptoms
After updating your iTunes on Mac to version 8.2 you are not able to connect/synchronize your iPhone with Windows in virtual machine. Windowd displays a message that USB device is not recognized. iTunes on Windows does not see your iPhone. Sometimes you can only get iPhone camera working in Windows.Cause
It happens because after latest update iTunes on Mac OS X grabs iPhone as USB device and will not release it to Parallels Desktop. As a result you can only synchronize it with iTunes on Mac or neither on Mac, nor in Windows.Resolution
