Networking :: No bluetooth modules in

I noticed a difference between my kernel 2.4.26 box running dsl and a recently installed DSL running 2.4.31;

In the kernel/net dir I have a whole less directories;

On the 2.4.26;

On the 2.4.31;

I am in need of the bluetooth ones..
Anyone knows why I am missing these directories?

Alex

Update: I found out that when I install net-modules.tgz I get part of the bluetooth modules back again.. but still hci_usb is missing

That worked.. thanks a lot
