menuconfig: can not select scsi device support

[robert rottermann]

Hi there,
I am working trough a book on embeded systems (embeded linux by J.Quade)
There in the chapter about building a new kernel is suggested to select Device 
Drivers-> SCSI device support -> a number of subslections.

Now, when I start menuconfig I find Device Drivers-> SCSI device support, but 
selecting it produces an empty page.

Why is that so?
Do I have to add other elements to the configuration process?

I am using linux-3.19.

Thanks
robert
