TAU arduino, whenever i upload the program it disconnects the board at the end

Well, i just got me a TAU, the arduino compatible board. So i've installed all the drivers for it and it does upload a program to the arduino, but the problem is that it disconnects it right afterwards. So i cant really see the program in action, or wheather it actually works. It is important to add that I have tried all sorts of ways to solve the problem, such as disabling the automatic USB disconecting option, installing the older versions of the drivers etc. I've tried it also on another computer, which is running windows 10(I personaly use windows 7), yet I've had the same issue.

What should I do.

Are you sure the code you uploaded us ok? Boards with native usb, like that one, can have the usb connectivity broken by a bad sketch. The procedure to recover from that depends on the board.

Probably best to take this to the tau forums/support - we have few if any people on these forums using those. Don't think I've seen anyone talk about it here
