Mine are working now with the latest CVS, one idea suggested to me was
to feed the IR transmitter's back into the receiver while running IRW.
But i also discovered mine does in fact flash red when a signal is sent.
Also i couldnt get all the drivers to build (maybe same issue as you) so
I just built mceusb and and am using the mce remote now.
