iTunes 'remembers' my iPad 2, since upgrading to iOS 5.0.1
I have noticed since accepting the iPad upgrade to 5.0.1, that iTunes 'thinks' that the iPad is still connected via USB, even when it isn't, and had been properly disconnected after the previous sync.
Clicking on the 'disconnect' icon in iTunes makes the iPad connection disappear, but it re-appears every time iTunes is started, whether or not the iPad is physically connected. Connecting and manually disconnecting the iPad each time iTunes is started makes no difference - the iPad connection reappears next time, regardless. BTW, iTunes is set to 'Backup to this computer', rather than 'Backup to iCloud'.
Is this behaviour expected? It's not (yet) caused a problem, but I get disturbed by any unexpected change in behaviour.
