If you hear the disconnecting chime, this has nothing to do with the sim or addon.
This is more likely a blunt USB comm drop.
This may be due to USB powersupply failing (wich doesn't seem to be the case as you already tried various USB connexion combinations)
This could be a USB cable issue or a Bravo internal USB board issue.
I suggest you connect the Bravo to another computer.
No driver, nor simulator required.
Just start the Windows joystick calibration utility, check that the Bravo is recognised and responding and simply move the levers for a while.
See if the communication drops again.
