Well, it's a desktop computer. Motherboard is an Asus K8U-X, by the way.
And at least the mp3 player is no more than a pendrive with an lcd and a
couple buttons ;-) Never though these to be power-hungry devices.

On the other hand, I've just tried and in the same port that at the
moment does not see the mp3 player, a simple standard pendrive _is_ seen
and recognized.

If you can't be good, be careful.  If you can't be careful, give me a call.
