This test is to be executed with two USB-to-serial devices (currently only FTDI is supported)
one of which must be plugged in through the MCCI Connection Exerciser.  This app is set to run
for 12 hours currently.  

The MCCI Connection Exerciser software (http://www.mcci.com/mcci-v5/devtools/exerciser.html) 
must be installed on a PC.  The script for stressing the cdacm driver's ability to handle
device detach/reattach events are performed with the following Windows batch file.

    @ECHO ON
    echo "CdacmPnPTest.bat"
    FOR /L %%y IN (500,10,5000) DO (
        call mcci2101.exe -dev 1 -verbose -hsattach -delay %%y -detach -delay 1500
    )
    ECHO Done... 

    pause

This batch file will call mcci2101.exe with delays started with 500 ms, increasing by 10 ms, until
5000 ms is reached.  Between values of 700 to 900 ms is the most stressful portion of the test.
