adb devices: not finding any devices

Alain

Following the suggestion from my previous post to update the device (OAK 4-s) to the latest firmware, I read the instruction here and entered adb devices and I get List of devices attached and nothing under it.

I did flip my USB-C cable end to end and flipped them (at both ends) but still no results. The camera is powered (blue light) and AFAIK, the cable is good. What else can I do?

When listing the USB devices attached to the MacBook Pro, I get this. Could the camera get the power but not be seen by the computer?

Just to add more debug infos. Things I have tried:

Tried various cables but apparently I only have one fat enough to power the camera
In the OSX/Control Panel/Privacy and Security, I changed the "Allow accessories to connect" to "always". Before doing this change, I did notice that when I plugged the camera, the pop up asking for permission would appear and then disappear almost a instantly.
Looked in System Information under the USB section and did not see the camera
Plugged the camera in another computer (MacMini) and it is still not showing up

Hey @Alain, I saw your post where you tried to update the OS on the device. Unfortunately the documentation recommended you to update to OS 1.6, which is not supported by your device and now your device is bricked.
Please submit an RMA form here and we will get you sorted asap, we will update the documentation to prevent this sort of SW bricking in the future. Please link this discuss thread in the RMA form.
