I'm confused .. sorry .. I'd try to help if I could get what you're saying better 
sowy
ok so i have an 3 ipods and 2 computers a desk top and a lap top
I keep my music and everything on my desk top computer b/c i have like 16 gb worth and dont want to take up space on my old lap top.
the ipod i use for some reason will not connect to my desk top computer(the computer will not even reconize it, wont charge the ipod anything) but it will connect to the lap top no problem
just to see if it was the ipod or desk top computer i attached an old ipod to it and it connected just fine
so its something specifically to do with my ipod touch and my desktop pc...
I can still get my stuff onto my ipod b/c of the home share that itunes allows for computers on the same network but its a pain b/c i had to transfer all my ish to my lap top which makes it uber slow
