Nano and Intel Macs (help!)

[quasialibi]

My new intel mac (MacBook Pro 2,5Ghz C2D, OSX 10.5) doesn't recognize my Nano. I'm quite sure it's a hardware issue as I noticed it didn't work on a clients intel mac (older CoreDuo model Macbook) running OSX 10.4. On my PowerBook (OSX 10.4) I never had problems and on PC's neither.

Is there a firmware update which could solve this problem pls?

In another thread (http://thecususergroup.proboards106.com/index.cgi?board=n1050installations&action=display&thread=738) somebody mentiones the same problem I think, but he/she thinks it's a software problem. I'm quite sure it isn't as it seems not to work only on intel macs.

Anybody with the same problem?

Anybody a solution?

THANKS!
