@bogon07: I already tried that driver, but nothing changed. And all other USB devices like mouse, keyboard, mobile and camera are working.

I reformated my computer some day ago. After I installed SonicStage 4.3 I plugged in the player, but there were no drivers detected. Windows just said it detected a "USB device" or a "Network Walkman", but then no drivers are found, and in the Windows Explorer I can't see the player. Sonicstage doesn't detect it, too. I formatted the player, I pressed the Reset-button. I deleted (and reinstalled) SonicStage and all of its registry stuff, I tried the Stand-Alone-Driver, but nothing happened. I'm using Windows XP SP 2, SonicStage 4.3, and everything worked before the formatting. Now I don't know what else to do...
