HP CD-Writer 9100 series not reading any CD's on WINXP



Please can someone help, :a
In device Manager on WinXP sp1 the CD-RW is displayed as
HP 000 CT-Wrytur; 91000.

But the actual model is HP cd-writer 9100 series 9150i

I can find the correct drive or upgrade for firmware, i have download all the software i can from the HP website which is compatible with my CD-RW Drive but can’t get it to read any kind of CD.
does anyone know of this problem.
