iPod Gen 1 Scroll Wheel M8541 recognized by computer but not iTunes

Hi!

I recently found my old original iPod Gen 1 with the Scroll wheel. Was the first one ever that worked with Windows. Connects with Firewire.

It still has all my old songs on it, it charges and plays those songs.

However when I connect to my computer, the computer recognizes it and shows it (and pops up the directory window) but it won't connect with iTunes 12.3.0.44 64bit and it stays on the 'Do not Disconnect' screen.

I have tried resetting it using directions off Apple's site and it works (the apple logo shows up after holding Menu and Play for a few seconds and it seems ro reboot), but that doesn't help with connecting to iTunes.

Any ideas for what I can do to get it to connect? Thanks!
