    To whom it may concern,

    following this instruction to https://docs.modalai.com/voxl2-unbricking/

    slide the SW2 switch into the ON position,

    but in QDL Tool, it shows QDL device not connected.

    I have confirmed that the USB-C cable works with other VOXL devices.

    Any suggestions or anything I missed?

    Thank you for your precious time on this.

            Hello, thank you for your patience.

            Can you run the lsusb command and let us know the output? (As the voxl is plugged in)

              Hello @will-huang-oksi,

              In response to @ZuraNeb as well, when running "lsusb" in your terminal with the device powered on and connected over USB, you should see the following device:
              Screenshot from 2025-06-02 11-50-13.png

              If not, I'd recommend filing an RMA and we can further debug the issue: https://www.modalai.com/pages/rma

                Hello @Nathan-Raras and @Nathan-Raras ,

                I don't see any Qualcomm device with running "lsusb".
                I also have confirmed that the USB-C cable is able to access another VOXL device.
                So I have submitted the RMA
                d45c5737-8bf3-4c8b-9e7d-851acbfe82a8-image.png

                Please let me know if any questions or suggestions.
                Thank you very much for supporting.
