Interesting. My initial plan was to use a USB Trace Viewer to watch
what happens during a a sync under win98, then do it again but install
something to the memory stick. Diff the results, etc etc.

I know there are more variables involved than what I mentioned above,
but thats the rough idea :)

Unfortunatly I havn't had the time to try this out, but hopefully
this weekend I should have a few spare cycles to play with this.

Thanks for the insight :)
