Possibe Device Error/MisConfiguration, Power consumption issue

erik

The question is with this workload of the pipeline, will I be able to run the same code with Oak-D Lite camera?

HI franva , yes, OAK-D-Lite has exactly the same computational resources as all other (rvc2) OAK cameras.
Thanks, Erik

franva

I need the same code to work on Oak-D Lite camera. How can I achieve that?

The Oak-D camera works with an external power supply and USB cable, but the Oak-D Lite camera does not have the socket for an external power supply.

franva

Also, I found that the OAK-D Lite and OAK-D cameras are always recognized as USB2 device even I use the blue USB3 cable comes with the OAK-D camera.

How can we solve this issue?

erik

franva Use Y-adapter. For USB2 - is that just for the discovery (before booting), or after booting as well?

franva

@erik yep, after looking around, I found the Y adapter might be the thing to solve the issue.

For USB 2, I do not know the OAK-D Lite camera has booting. I thought the booting is only for POE model?

But mine is not POE model.

What does Discovery here mean?

How to find out whether it is the discovery or booting?

erik

franva Where do you see it's "USB2"?

@erik

Here it is:

[ 270.646853] usb 1-1.2: USB disconnect, device number 8

Hi franva,

could you please check the USB speed after booting with device.getUsbSpeed() to make sure?

Thanks,
Jaka

franva

jakaskerl thanks Jaka, I'll add the code.

so what is the return value for USB3 and USB2?

jakaskerl

I think SUPER for USB3 and HIGH for USB2.

franva

Hi jakaskerl

Here is the value from dmesg

And the value from device.getUsbSpeed() UsbSpeed.SUPER

Then I am confused, why from the dmesg ,

[ 6652.012692] usb 1-1.1: new high-speed USB device

It shows high-speed(USB2) first then shows the SuperSpeed(USB3)?

Why is it like this?

erik

franva 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, Erik

franva

okiee, thanks for letting know.

This question can be closed now.

How can I mark it as resolved?
