*Supporting multiple cards now.

Some issues:
*Not yet handling unplug event
*Can only switch between multiple devices, but not control them all in the same time.


Recently I am working on this:
To generate script file for our android program to read and process.


Neue Version Decision-USB-Android


Info 5-2020:
Only the Sample Code for Input and Output for invocation of the API provided
by DG should be delivered to our clients since they have to integrate their own App.
The complete source code of our launched App should not be given to the clients.
Time is required, two to three week I assume, for amendment of the source code before providing it to the clients.
The clients can use the app not the source code if they want the code at this moment.
