I have a third generation 40GB iPod which I've been having some trouble getting to work with Windows 7 (RC).
iTunes and all other relevant software is installed correctly and indeed, the iPod itself works if the device is plugged in as the system reboots. However, after ejecting and using the iPod, plugging it back in results in a USB Device Unrecognised error and the iPod remains on the main menu before switching to the Charging screen. Only rebooting and having the device in from before Windows is running (where it is recognised by the BIOS) works.
It previously also worked fine on my Windows Vista installation on the same hardware and trying different ports has no effect.
How can I get the system to recognise the device without needing to restart?
