OAK-D CM4 PoE - Device Not Found

purpledread

I logged into the Raspberry PI on the device and tried to run the demo, but i get the following eror:

python rgb_mobilenet.py

Traceback (most recent call last):
File "/home/pi/depthai-python/examples/MobileNet/rgb_mobilenet.py", line 56, in <module>
with dai.Device(pipeline) as device:

RuntimeError: No available devices

Is there something you have to do to let the program know to use the USB3 for the device?

From what I'm reading online, it looks like there should be a device /dev/ttyUSB*, but there are none.

Also running lsusb:

After flashing the device, I accidentally put the small little jumper too far to the left and it wasn't connecting the two left pins.

All working now.

Hi purpledread ,
We apologize for this issue. Could you please send an email to support@luxonis.com? Please also provide purchase order, it might be an Cm4-POE from that batch, which has an overheating issue of the USB hub.
Thanks, Erik
