Windows doesn't recognize my Plextor PX-504UF

Hi.

When I have connected my Plextor PX-504UF to IEEE1394 or USB2.0, Windows XP recognize it as Plextor PX-504A. Nero 6.6.0.3 think it’s a Plextor PX-504UF and says it can burn with 16x, DVD-R DVD-RW and so on, but it can only burn with 4x and DVD+R(W).
Plextor’s Plextools Professional v2.18 recognize the burner correctly.

Can someone help me out here?

Thanks!

I’ve now tryed to upgade the firmware. No luck.

Oops, thats wrong. Nero 6.6.0.3 think it’s a Plextor PX-504A.

I’ve figured out the problem. (Damn this forum is dead.)
