This is the most comment cause for error in compiling custom kernels 
I've seen (the OP is around the 20th person I've seen while 
semi-actively watching the lists for the past year or so).

I think that the questions and current lists should have FAQs about this 
particular "error", or maybe the example GENERIC kernel config file 
should move ural to the wlan section and have a big warning posted next 
to it stating "ural requires both USB and wlan support".

Just my thought though on the subject..
