Sorry about the trouble here. So I see that the device is connecting at USB2 rates (Usb speed : High/480Mbps). So do you know if your host supports USB3, or if this is a USB2 port? And which host is it?
So I'd recommend trying:
python3 depthai_demo.py -fusb2 to see if this clears it up.
I'd also recommend restarting the host in case something is out of sorts with USB when interacting with DepthAI.
One other note:
You could try running Gen2 instead, say with a code sample from here:
So our Gen2 API is now our default, but some documentation point to this DepthAI 1.x (or <1.x) instead of Gen2 (which is 2.x).
Thanks and sorry again about the trouble,
