Hello.
I did everything as instructed, but the error still occurs.

I also tried to follow the instructions given here.
That doesn't mean the camera isn't working
If you add maxUsbSpeed=dai.UsbSpeed.HIGH in depth-experiment, it will work.
Please help me
Thank you

Hi yeo
Please update to the latest depthai and depthai_sdk versions. What is the actual error you are getting? Have you tried switching out USB cables or trying different USB port?

Thanks,

After updating to the latest version, the following error appears.
As stated in the error, if I run "python3 install_requirements.py", I will get the same error as I wrote at the beginning.

Depthai version installed:  2.22.0.0
Version mismatch between installed depthai lib and the required one by the script. 
                Required:  2.21.2.0
                Installed: 2.22.0.0
                Run: python3 install_requirements.py

Hi yeo
Try adding the --skipVersionCheck flag. Though it looks more like a usb problem considering it works with usbSpeed.HIGH - any chance your laptop doesn't support 3.0? Also what happens if you start the device with
with dai.Device(usb2Mode=True)?

Thanks.

The USB I'm using seems to be 2.0.
However, it is strange that the first mentioned error occurs whether it is USB3.0 or USB2.0.

Hi yeo
Could be that there's a bottleneck somewhere - be it the cable you are using or the port on the host machine. I think checking if the color of the USB is blue is a good enough indicator of bandwidth capability. Both the cable and the port have to be blue.

Thanks,

Even if I try to find USB3.0 and test it, I get the same result.
I checked both port and USB are blue.

Hi yeo ,
Could you paste the full terminal output when you run depthai_demo?
