[mythtv-users] mceusb and Formosa (147a:e042) transmit not working

[David Dempsey]

Hi-
  I have a Formosa MCE IR transmitter/receiver.  The receiver works fine, but the transmitter does not work.

  After loading mceusb module in debug mode, it seems that the request transmit blaster mask is incorrect from irsend.  

  Upon loading mceusb it seems to detect a transmit blaster mask of 0x3 but when I issue a  'irsend SEND_ONCE DCT2000 FFWD', the requested mask is never 0x3.  I can change the mask irsend uses by issuing 'irsend SET_TRANSMITTERS <num>'

  Any ideas?

  Here is the usbmon output during 'irsend SEND_ONCE DCT2000 FFWD'
