I think u'd take one of the buses from Subang to Kelana Jaya LRT, then another one from KJ LRT to 1U and stop at the bus stop near KDU. There's no direct connection.
But I don't remember the bus numbers, sorry. [edit: I think it is bus# 623 from SS15 to KJ LRT, and T43 from KJ LRT to 1U, but pls confirm with the experts in that RapidKL thread] Try posting the same question over in that thread, our resident "usj.com public transport minister" will give u the answers, hehehe
