Hello,
I have flight deck, Is it possible to interface addition sensors to the flight deck that are powered via USB. As there are no USB ports on the deck I don't know how to attach the device. 
Device that I am looking to attach is a RFID reader and a sensor from Intel realsense family. Both of which needs USB 3.0

Thanks

We offer an add-on board that exposes USB2.0 but not 3.0 as the add-on connector is a 2.0 port.

VOXL has the option to be used as a USB3.0 HOST port  using a custom cable, but it's not a cable that is easily found...  it's somewhat of a fringe setup --> [this cable pinout](https://docs.modalai.com/cable-datasheets/#mcbl-00019)  using [this port](https://docs.modalai.com/voxl-flight-datasheet-connectors/#j8---usb-30-otg), here's some [more info](https://docs.modalai.com/voxl-as-usb-host/)
