Cannot "Beep the Beeper"

Problem: Using Windows SDK, I am unable to get scanner to respond to SET_ACTION (6000) method..."Beep the Beeper". The return status is 0 indicating success, but no beep.

 

Configuration:

OS = Win7 Pro(32)

Scanner = Symbol LS3578-FZ

CoreScanner version = Motorola Scanner SDK 2.3.2 API

Mode = IBM-Hand-Held USB

 

Notes:

While the C++ application can detect and retrieve asset tracking info, it cannot "Beep the Beeper" either. Although, it says it completes successfully.

I watched the help videos on YouTube.

I also tried the 2018 method with the same result.

I noticed that the cradle shows up as Scanner ID = 1 with a GUID while the actual scanner is ID = 2 with no GUID?

 

Any help as to what I am doing incorrectly would be greatly appreciated.
