Sony Vaio PCG-X9 and Aopen 5232 Combo External Drive

Having some driver issues with this setup. Can anyone help.

Using Windows 98 SE on this laptop. It recognises the drive being plugged in to the USB connections but it doesnt find drivers for the cd drive. Are there proper drivers for the cd drive or is it because its not USB 2 compatible laptop/OS.

Please help asap !!
