I am following https://docs.modalai.com/voxl2-usb3-uart-add-on-user-guide/
I have a samsung usb storage (https://www.samsung.com/us/computing/memory-storage/usb-flash-drives/usb-3-0-flash-drive-bar-32gb-muf-32ba-muf-32ba-am/)

formatted as `Ext4` . But no detected usb storage on VOXL2.
The connection is exactly the same as the example.

```
voxl2:/$ lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 10000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M
```

Version of VOXL2
```
voxl2:/$ voxl-version 
--------------------------------------------------------------------------------
system-image: 1.7.8-M0054-14.1a-perf

hw platform:  M0054

```

Any thought?

@voxltester , does VOXL2 detect any other devices (USB2.0, USB3.0) using the same USB3 add-on?

@voxltester , I am sorry to hear that - if you are not able to get any devices working on the USB3 port, perhaps the add-on board is not functioning correctly. You may want to submit an RMA and get a replacement. www.modalai.com/rma

@Alex-Kushleyev
Thanks for the information. What kind of USB3 add-on will work for this?

@voxltester , my understanding is that the board you have originally purchased should work for this, so it might be defective, if it is not able to detect any USB devices.

Maybe @Vinny can take a look?

Hi @voxltester 
Are you able to post a high res photo of the USB breakout board, both top and bottom?
Could save you the time and hassle of an RMA with a good high quality photo I can inspect.

The board was tested and passed before shipping, but these boards do have some small parts on that that are susceptible to damage if the board is dropped or if a tool or other item hits into it.

Thanks!
