2D Scanner

The USB scanner ( model YHD-M200 ) in the link bellow, has small button at the bottom which activate scanning. We need to activate scanning programmatically without pressing device button and read the output. I assume the same approach is used for many other scanners.

A Freelancer has to provide source code which does the above.

How it works at the moment:
1) Press button and keep it pressed, the scanner is activated
2) Once button released - scanning stopped
3) Once scanned successfully or failed scanning - the scanning gets deactivated.
