Boot/reset button default behavior?

[bigjdunham]

I'm having trouble getting my T-Impulse to enter DFU mode. I think I might have a malfunctioning boot (or reset) button on my T-Impulse which is causing issues. What should be the default behavior for each of those buttons if I just press them normally?

There is little feed back on this device that I can find but for mine the sequence:- hold B; press and release R; release B the unit does not restart 'factory demo program'. I assume this is now in data load mode but for me the Win10 machine is not detecting it to be connected after loading drivers.
