Sorry, I don't have your usb wifi card on hand , so I can't give a try
but could I know why you can't used build-in wifi modules
BTW base on your error message , under the "/lib/modules/<kernel version>/build" is kernel source
so I think you are not install fail ,it should be build module fail when it try to find kernel,
I think you could do this by below two way
1.copy kernel source to below message mention folder and re-build it
2.build it at host(x86) device , used cross_compiler( you could find it at
http://www.plugcomputer.org/downloads/d2plug/index.html) and
modify your usb module make file , to let it to find your d2plug kernel source at host PC, than re-build it
