Even behavioral semantics are different. In addition stacks like USB3 and bluetooth are missing. These are non-trivial and complicated by the fact that not all devices behave strictly as per the standard. Scores of device variants need to be tested, idiosyncracies addressed etc. Biggest of all debugging in the kernel space is an art by itself. Sometimes one will have to forget about life to get something working. Regards, Moinak. ========================== http://moinakg.wordpress.com http://moinakg.github.com/pcompress/
