No DepthAI device found

rpurcell

This has probably been covered in a thread but I can't find one with similar problems.
I'm using an OAK-D-WiFi on Oracle VM VirtualBox - Ubuntu 20.04.2
I'm using the supplied usb cabling.
I've run and satisfied install_requirements.py
When I run $ lsusb my terminal returns "Bus 001 Device 003: ID 10c4:ea60 Silicon Labs CP210x UART Bridge" which is the OAK-D-WiFi.
If I try to run ./depthai_demo.py I get "No DepthAI device found!"
If I try to run ./depth_demo.py -fusb2 I get "depthai_demo.py: error: unrecognized arguments: -fusb2"

I encountered similar problems when I tried this on my 2014 macbook pro.

Anything else I could try at this point?

Hello rpurcell ,
we apologize for the inconvenience, but for the VM there are a few additional steps you need to complete, instructions here. Also when running lsusb you should see Movidius Ltd. Movidius MyriadX. Hope this helps!
Thanks, Erik

Thanks Erik. My apologies, I somehow missed the virtual box instructions. I will try those.
I switched to virtual box because I was getting device not found on my Mac. Any suggestions for this problem on Mac. I have everything installed correctly I believe. (output from my Mac terminal is below)

rpurcell Hi, have you tried the following steps here?

rpurcell

Hi, yes. And the extra included trouble shooting listed here.

rpurcell thanks for letting us know. I don't immediately know (I don't work on mac), so let me ask internally and circle back.

Just to close this thread:
I now have everything working.
The issue was my ignorance of connectors. I simply plugged in the wrong cable.
I am a newbie to device related things (and yes, connectors) so when I opened the OAK-D wifi package/box I installed all software as directed and plugged in the first of two cables that were included in the box. Turns out I plugged in the wrong cable. But when lsusb returned acknowledgment of a plugged in device I jumped to the conclusion my problem was either install based or a damaged device. When lsusb returned "CP2102N USB to UART Bridge Controller" this should have been a flag to me. I just didn't understand the flag. As Erik mentioned previously what should have appeared was 'Movidius Ltd. Movidius MyriadX'.

This is on me. Totally. An extremelly silly error. The device is amazing.
What could have helped me as a newbie to get to a solution more quickly was a more explicit listing on the landing page of the cables included in the box. Labelling of the device image ie:(connectors) on the landing page would also have helped me to better understand the device.

Thanks for your help. The suggestions above are just meant to help the next newbie.

Great that you got it working rpurcell and good point. Thanks for the suggestion, we will add that to the landing page!
Thanks, Erik
