I've just started testing the Relay Cape (CBB-Relay) and am having an issue 
with one of the relays. I used the device tree overlay provided by the 
manufacturer and it is loading fine. I can use Bonescript to turn the Relay 
K1 (P8_18) on and off just fine. When I try to do the same with Relay K2 
(P9_27)  I get a Bonescript error that appears to indicate that pin P9_27 
is already in use. I have disabled HDMI and eMMC using uEnv.txt. I am 
executing the node.js program using root login. I am using a Rev C board 
with a 2A 5 VDC supply and running Debian build 3.8.13-bone69. Any idea 
what is using pin P9_27 and how I can free it up ? Thanks in advance.
