  Hi @serviceberry
  From a HW viewpoint (I am HW team) that sounds reasonable to use the hub the way you suggest. But I know for a fact from personal experience the Boson's are very dependent on VBUS rise times, and a very fast rising 5V supply may not allow it to enumerate properly. We have had an instance in the past where one particular VBUS port rose really fast, and the Boson did not enumerate until we slowed it down. It's one of those situations that may require testing to check. Our J3 10-pin host port has a nice moderate rise time that allows Boson to enumerate. So, when using a Hub, check the VBUS rise times compared to J3.
  I do NOT expect J9 USB-C OTG port to work with Boson.
  The Snapdragon SOC is very smart, and when in OTG mode, it will not provide more than 500mA to any device that enumerates as USB2 which I am lead to believe how the Boson enumerates. if the Boson could enumerate as a USB3 device and the drivers were all present in the Kernel for this, the Snapdragon will give it 900mA over VBUS letting it boot but I think this is a non-starter without the Boson being able to do that.
  Our Boson kits use USB2 only and we provide 1A support to enable them to work without requiring enumeration to negotiate more current, hence why they work on the J3 ports and other expansion board ports that have more than 500mA: https://docs.modalai.com/expansion-design-guide/#usb-expansion-over-j3--j5

  Hi,

  VOXL2 version.jpg

  I need help connecting IP camera to Ethernet and HUB add-on.
  The conclusion is that GCS does not ping IP camera.
  The system configuration is as follows.

  Please tell me how to connect from GCS to IP camera.

  Thanks,
  JS, Kim

  @stevedan @bensusana I'm also facing this issue. Have you been able to solve this?

  @qqa , we have document how to achieve folder-level encryption on VOXL2 here : https://docs.modalai.com/enabling-file-encryption/ . Please let us know if you have any other questions.

  @TomP Oh, yes, this is all great news! Very exciting to hear! I will send an email to your account with some follow up questions.

  Unbricked! Here's some context/advice for anyone trying to do the same. If you purchased a cheapo STLINK V2 from Amazon as I did. Picture below...

  $0 Fix:
  What may very well happen to ya, is the RESET pin doesn't work. In this case you will need a friend. With said friend, you must dilligently connect to the board using Under Reset Mode and Hardware Reset. The second your homie clicks the connect button, you, the bricker of the board must move your jumper cable from the RESET pin which is 3.3V to an open Ground, leave it for exactly 1 second, then move it back to RESET. This should work like a charm, but may require one or two tries to get the right timing. See instructions below.

  $10 Fix:
  Program a Pico/Arduino to do your 1 second ground for you.

  $78 Fix:
  Buy the real STLINK V2.

  Hi @Amir-Avni,

  Does your silkscreen on VOXL2 show M0154 or M0054?

  If M0054, it's 'hard coded' as an output only... behind a uni-directional level shifter.....

  If it's M0154, there's a directional level shifter in front of that GPIO that allows us to (with a kernel tweak) switch between UART and SPI.

  By default we are configured for UART use case, and the level shifter is set to allow an INPUT, by setting GPIO 67 low (as default), which is setup in device tree here, see "67" in modalai,gpio-init-output-low
  https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/v1.8.02/recipes-kernel/linux-msm/files/dts/common/m0xxx-modalai-gpio.dtsi?ref_type=tags#L12

  To enable VOXL2 J10 pin6 (gpio46) as an input, make sure gpio67 is set to low

  ok I found the problem...
  the Cube Serial inteface are driven by TXS0108E Level Shifter powered both side with 3.3 volt making it marginal for the Voxl Primary Serial interface. Switching to secondary interface on the Voxl made it work correctly.

  I sent a request for a change in the WIKI to reflect that configuration
