      @hanktttop said in Cardputer COM Not Working:

      @ajb2k3 Yes, I tested the first time this was suggested. In fact, the first cable I was using was just for charging a portable gaming console. Then I tried a few more, inclund cables for smartphones, external drives, etc. And I tested then on their specific devices, everything normal.

      No idea why the cheapest one worked on cardputer, though.

      I'm glad you have it working now...mark this cable up as Cardputer saver cable

          • Connect Cardputer on PC
          • Open the Device Manager
          • View > Show Hidden Devices
          • Try Hold G0 and click RST until the USB JTAG becomes enable

            The issue is that the drivers are not being recognised by Windows 10 when the cardputer is not connected and so when it is connected via USB and G0 + RST are pressed USB JTAB is not activated. There is a permanent yellow triangle next to whatever flavour of CP210X driver is installed.
            I now believe that the CP2102 driver not being recognised by Windows 10/11 is a read herring and I wasted a lot of time in research on the web to try to get it going. In the end I got a 'fat' USBA-USBC cable capable of fast data and 60W power charging.
            I then did as you suggested and immediately Windows recognised the device and assigned it a COM Port.
            Many thanks for your help

              The CP210X is not used as the StampS3 has it own internal USB >TTL converter.

                I was also getting the "not in bootloader mode" error as well - and with a very trusted USB-C to USB-C cable! Then remembered I had the FlipperZero box with me and tried that cable - which WORKED! So, this is not the main reason to buy one obviously, but if you do have one and you're experiencing this error on a Mac (M1) then this is something to try. The "not in bootloader mode" error is a little misleading in this case as the cardputer was doing its part, but the first "trusted" cable was not!

                  Fiz tudo isso e não resolveu. Entretanto, coloquei inserir o cabo e manti pressionado o botão a baixo do adesivo e cliquei em instalar o Nemo. Mantive pressionando até o final da instalação. Após finalizar tudo, eu soltei. Funcionou, graças a Deus!!!

                    @ajb2k3 Thank you for that information. I had seen somewhere that a CP2102 driver for windows was necessary, that appears to be not required. After numerous tries with a USB A to USB -C cables which had the data and power wired through, I went and bought a fat cable capable of 60W and fast data - as soon as I pressed G0 and inserted the cable windows immediately assigned a COM Port.
                    I am very grateful that you pointed out that the Stamp-S3 has its own built USB>TTL converter!

                      "I had a similar issue with not recognizing the COM port, but after some testing, I found out that on my laptop, the cardputer's COM port only recognizes when I connect it through the laptop's USB type C port."

                        I was having the same problems with my CardPuter not being recognised when connecting to USB with the Go button depressed but after reading through this thread I finally tried another USB 'C' cable and the Windows 7 system finally tried to install drivers for the unit.
                        It installed one USB driver but failed to install the 'USB JTAG/serial debug monitor' driver.
                        Where can I find this driver to download for Windows 7 ?
                        At the moment when I hit the 'Burn' button on the Burner program I get an error box pop up which says 'Get mac failed'

                          Perfect, I had the same problem after installing UIFlow 2.0, it didn't detect the correct COM, using this method of holding the btnGo and then turning on the device the correct COM started working again (remembering that by doing this, the device remains with the screen disconnected, but communication works again). Thank you very much.
