USB Keyboard is not working with a custom kernel

[??? ????]

Hello list,

I've custom-built a kernel for a FreeBSD 7.0-STABLE amd64 system.
The kernel file (/sys/amd64/conf/KERNEL) is shown below:

With this kernel, whenever I connect a USB keyboard, I see on the console an alert ("USB keyboard device this and that, connected to ....") and even the make/model of the keyboard is shown, but the keyboard doesn't work. The Num/Caps locks work (I mean, the light on the keyboard alternates between ON/OFF whenever press on the keys).

Anyone knows what's the problem? And how to fix it?

Thanks in advance.
