lets go for some additional useless info... ;-)

I thought that the MOTU Traveller has the following Stream syntax  
(haven't mine here, so cannot test at the moment, but I'm pretty sure  
about this):

"MOTU Traveler" Input Device
   Streams: 5
      0  channels 8	// analog   	in 	(AudioIn.ar((1..8)))
      1  channels 2	// SPDIF(?) 	in 	(AudioIn.ar([9, 10]))
      2  channels 2	// AES(?) 	in 	(AudioIn.ar([11, 12]))
      3  channels 2	// Phones(????) in 	(AudioIn.ar([13, 14]))
      4  channels 8	// ADAT		in 	(AudioIn.ar((15..22)))

"MOTU Traveler" Output Device
   Streams: 5
      0  channels 8	// analog   	out	(AudioIn.ar((1..8)))
      1  channels 2	// SPDIF(?) 	out	(AudioIn.ar([9, 10]))
      2  channels 2	// AES(?) 	out 	(AudioIn.ar([11, 12]))
      3  channels 2	// Phone 	out 	(AudioIn.ar([13, 14]))
      4  channels 8	// ADAT		out 	(AudioIn.ar((15..22)))


So this would enable all your ins/outs:
s.options.numOutputBusChannels_(14).numInputBusChannels_(14)
s.options.inputStreamsEnabled_("11111").outpuStreamEnabled_("11111")

inputStreamsEnabled
- A String which allows turning off input streams that you are not  
interested in on the audio device. If the string is "01100", for  
example, then only the second and third input streams on the device  
will be enabled. Turning off streams can reduce CPU load.

outputStreamsEnabled
- A String  which allows turning off output streams that you are not  
interested in on the  audio device. If the string is "11000", for  
example, then only the first two output streams on the device will be  
enabled. Turning off streams can reduce CPU load.


hope that helps
