current kernel compile error (USB)

Hi everybody,

I have problem compiling "buildkernel" for two days. Error message I 
receive is below:
----

===> usb
make: don't know how to make usbdevs_data.h. Stop
*** Error code 2

I do not understand about coding. So, is there anybody who can suggest 
me something?

Regards,
