'__stream_asset_storage' (X_LINK_ERROR)

juni

Hi, I'm tried to run depthai_hand_traker/demo.py and got '__stream_asset_storage' (X_LINK_ERROR).
My camra is OAK-D-Lite, i'm very begginer of depthai got last week. Anyone help me?

Hello juni , are you using a working USB3 cable? If it's USB2, you need to https://docs.luxonis.com/en/latest/pages/troubleshooting/#forcing-usb2-communication. You can check by running in debug mode - you can also copy the whole log when running in debug mode.
Thanks, Erik

Wow, it's just cable!!!
Thanks erik!!!!

I'm getting a similar issue when I try to create the pipeline in C++ with dai::Device device(pipeline);. I'm running through a USB C cable that should support higher than USB 3.0 speeds from what I understand. I'm creating an input and output XLink stream, and my exact errors are:

terminate called after throwing an instance of 'dai::XLinkWriteError'
what():  Couldn't write data to stream: '__stream_asset_storage' (X_LINK_ERROR)

I'm fairly new to this hardware and would like to reopen this thread to figure out the issue. I've tried with various USB C cables in all of my laptop's ports (USB 3.2 Gen 2 Type C ports) and it doesn't work, but I don't think that the cable is the issue.
