Can I use USB 1.1 to charge or sync the iPod?
For most models, yes. Although it was not officially supported by Apple until October 12, 2005, you can charge and sync iPods that support USB 2.0 by USB 1.1 as well — with the exception of the iPod touch models, which only support USB 2.0. However, USB 1.1 is substantially slower than USB 2.0, and consequently charging or synchronizing an iPod using USB 1.1 will be substantially slower as well.
