Hey lee initially, it's USB2 when device is waiting for a connection/pipeline. When you connect to the device, depthai uploads the depthai firmware to it, which will try to enable USB3 speeds.

Thanks,
Oskar

Even if I run depthai-viewer and plug in the camera, it connects to usb2, is there anything else i need to do to run it?

OskarSonc

Did you set the udev rules? Can you try some other good USB3 cable/port? More info here:
https://docs.luxonis.com/hardware/platform/deploy/usb-deployment-guide/

You can try running something like this also:

import depthai as dai

with dai.Device() as d: 
    print("USB speed:", d.getUsbSpeed())

OskarSonc depthai-viewer runs based on python3 but with command input as terminal, can you send it to terminal command?

OskarSonc

Run this directly in terminal (no .py file needed):

python3 - <<'PY'
import depthai as dai
with dai.Device() as d:
    print("USB speed:", d.getUsbSpeed().name)
PY

HIGH / 480M means USB2, SUPER / 5000M means USB3.
If it still stays on USB2 after app start, it’s usually cable/port...
