Hey Xing,
Can you please test IOIOLib 5.07 and IOIODude 1.03 on El Capitan and Ubuntu
14.04 and let me know if there are still any issues?
In addition, can you provide some feedback about whether or not you needed
some special udev rule to disable modem-manager messing with the IOIO to
get it working? I cannot reproduce this on a VM.

Thanks!
