The first and third errors are not always the same, but looping error is always the same.
3ac553f doesn't fix this issue.

Re-launching doesn't solve this problem:

$ source ~/apc
_ws/devel/setup.bash && rossetip && rossetmaster baxter && roslaunch sphand_driv
er setup_gripper_v8.launch left_gripper:=true
...
terminate called after throwing an instance of 'std::invalid_argument'
  what():  Cannot set to channel 0 on Multiplexer 70. Check I2C cable connection

Current solution: re-plugging all I2C cables...
-> sometimes doesn't work. Then rebooting is needed.
