      Hi,

      On one of our VOXLs I tried to access it using adb shell, but it couldn't find the device. It also doesn't show up when I use adb devices.
      When I used this procedure (that has worked on another device before), it keeps saying Waiting for fastboot....

      Is there another method?

      Thanks in advance!

        @SHofmeester What does the device enumerate as with lsusb?

          Hi @tom,

          I tried lsusb both regularly and with the fastboot method from the unbricking procedure. But it didn't recognize the device. The result of lsusb was the same when it was plugged in and when it wasn't plugged in. I tried with another VOXL and it did recognize it.

            @SHofmeester Interesting, can you try with a different USB cable / port? How are you powering your VOXL?

              @tom
              I'm powering the VOXL with the standard power module delivered with the VOXL.

              I have tried different cables and ports, but the results are the same. Those are cables and ports do work with another VOXL we have.

              Is there a specific location on the board we can measure with a multimeter to see if the VOXL is still functioning correctly on a hardware level? Or is that too difficult or dangerous?

                @SHofmeester I would recommend submitting an RMA: https://www.modalai.com/pages/rma

                  I had the exact same problem on my Ubuntu 18.04 machine with the VOXL 2.

                  To fix this, I had to restart the adb server with sudoers permissions. Maybe this will help:

                  adb kill-server
                  sudo adb start-server

                    @SHofmeester Another thing I just thought to try::

                    run sudo dmesg -wH and see if you see the VOXL enumerate when you plug it in to your machine
