What's running on the board? I'm not familiar with it or arduinos at all but it looks like it's being
detected and then disconnected. Are you trying to program the board through USB? If so, and since
it's detected when you reset the board, my guess is that it's got some kind of bootloader that is
initializing the UART->USB adapter and passing control to whatever firmware is already loaded, and
that firmware is not driving the UART/USB adapter. If that's the case the board's manual should tell you how
to program it.
