been getting this error for awhile now, i searched all over the net for the solutions and tried various things like reinstalling itunes and it didn't work, so unplugging and or changing where my iphone is plugged in that didn't work, but i have not been able to sync or backup my phone for over a week

64bit itunes
windows7 Pc

if anyone needs anymore info from me lemme know

but i have tried all of the obvious restart your computer stop all the apple related programs and start them all over again, change usb port type solutions, and i have no clue how to fix this

I get the same error with my iphone and ipad. 2nd time always works though...
