Review comment:
For me this line looks perfectly OK.
I don't see anything that could be split.
Same approach is use few line above where `lsusb` is piped to `cut` and here
`system_profiler` is piped to `awk` in very nice way including error
redirection to **/dev/null**
I don't have OSX to check for system_profiler output but awk part is very
clear and there is no single character I would written better.
@vrahane please reconsider
