[adm5120] fix support for 2.6.38 kernel

This patch fixes the following issues I encountered while compiling kernel 2.6.38.8 for my Omnima Embedded Controller/Edimax BR6104KP:
    - kernel comes up with machine selection during build, even though everything was properly set in menuconfig
    - USB api changes
Successfully built and tested with r29755.
