Our VOXL network is not showing up. 
We can't interface with it through the ADB tool. 
The flight control module, however, does work. 
What are some ways we can check if the VOXL on  is fried? 
if the VOXL is fried what are potential ways to move forward?

@Sravan-Parakala What do you see when the voxl is connected to your host pc via. micro usb and you run `lsusb`?

@Sravan-Parakala Are you running in a VM? It's abnormal to not see the device get detected at all

@tom we tried it with linux as well. also when we use another board it does show up.

@Sravan-Parakala If nothing shows with linux either then it sounds like the board is bricked and I'd recommend submitting an RMA https://www.modalai.com/pages/rma

@tom we are in a situation where we have 2 identical boards. one board has a working flight control board and the other has a working VOXL. is there any way we can use them together for the time being?
