pyocd-flashtool doesn't work at all with RPiv3

pyocd-flashtool doesn’t list any devices I’ve connected. Instead mbedls works fine. pyocd was clean clone from head of master and installed with command python setup.py develop .

This might be similar issue than #241, and there was mention that #262 should fix the problem, but I’ve still problem.

What I used:

~/pyOCD/ $ git rev-parse HEAD
48610ba219264d5306fa68bef2cd4ca89ef82067
$ uname -a
Linux raspberrypi 4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016 armv7l GNU/Linux`

What happens:

~/pyOCD/ $ pyocd-flashtool -l -d debug
DEBUG:root:Exception getting product string: The device has no langid
DEBUG:root:Exception getting product string: The device has no langid
DEBUG:root:Exception getting product string: The device has no langid

$ mbedls
mbedls -j

running with sudo in linux seems to work. So issue here is just lack of documentation. Please add some mention that this needs sudo access when running in linux and introduction how to run without sudo .
