I use a Dragon Professional Individual (version 15.30) with a new Speechware 3-in-1 TableMike. I primarily use Dragon to dictate emails in Outlook.  Every day the TableMike will work fine for a while, and then stop working for no apparent reason. In order to get the mic to respond again, I have to either unplug the TableMike USB and plug it back in, or close the Dragon application and then reopen. It will work fine for awhile, then stop responding again.  When the TableMike stops responding to my dictation, I am unable to dictate in DragonPad as well. 

My Dell destop computer is brand-new, with an Intel Core i7 processor and 16GB of RAM. I run Windows 10.

I have tried different USB ports that doesn't resolve the problem.

I also tried to create a different user profile in Dragon. That did not resolve the problem. 

The Nuance tech support folks tell me the problem lies with the TableMike, not their software, because when I go into the sound settings in Windows 10 and test the microphone it does not respond.

Thanks in advance for suggestions.
