Hello I'm literally having the same issue, I have bought the team xecuter sx pro and just received it yesterday.
My nintendo firmware is 9.0.1 at this moment, with nintendo edition sd card 128gb and have formatted to fat32.
Have downloaded the sx os 2.9.3 beta, boot file.
When I press the power button and the +volume button the dongle shows 1 sec of blue light but that is all nothing happens.
Is my dongle faulty? Or what other alternatives that can be done?
Thank you
