hi,
usualy when plug to OBD (power it with 12V) the blue rectangle has to be shown on as a selftest of the computer inside the interface.
but mine does not turn on any led when plug to 12V, but if i plug then the USB to the laptop it`s showing red light rectangle,
the virtual COM port is prsent (the FTDI) but when i try to test hardvare red is blincking and software is returning the message " No VCI Found"
that means the MCU inside interface does not reply.

does anyone here is having the same experience or issue as mine? i have allready two cables with same behaviour.
what is the receipt of the remedy ? is it hardware failure or the MCU does not boot and has to be refirmwared by JTAG?
i say thanks in advance!
