I'm getting this issue as well on android 5.1 (LG G3). As far as I can tell, 
its caused by a failure to get a list of files in the "/dev" folder in the 
"Driver" Class.

mDevices = new Vector<File>();
File dev = new File("/dev");
File[] files = dev.listFiles(); //Error on 5.0 + devices, returns a null object

I assume this is because the security permissions for accessing "external 
storage" changed in kitkat, and that the fix lies in implementing the new 
storage api for lollipop.
