I had this error occur today when attempting to update my iPhone 4 to iOS5. I'm using the latest iTunes (10.5) on Windows 7. Here's how I resolved it:
Re-try again, then run Console for any further details.
For advanced solution try to Download and install OS X USB Debug Kits which will provide more information about USB device and interface detection, driver and interface matching, driver loading and information generated as a result of normal and abnormal conditions.
