Driver missing (Code 39)

i just got a problem with my DVD ROM and CD RW. And the problem is they cant be used. And I use Windows XP.

I tried to re install but I’ve got the error message: “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). “

but finally I’ve got the solver:

all you have to do is:

Go to menu Start and select Run.

Type regedit and select OK.

Remove Upperfilters and Lowerfilters values of the following key to the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Restart your computer to save all configuration.

solved! thanks
