Hi,

I have an application running with OAK-FFC-3P without problem on laptop as SuperSpeed USB device. But when it runs on Raspberry Pi 4 USB 3 port, it always crashes after showing up as SuperSpeed device for less than a second. It runs no problem on USB 2 port. But USB 2 is too slow for my application.

I am pretty sure this is

  • NOT a cable issue, I tested with numerous USB 3 cables and the issue wasn't showing until raspberry pi.
  • NOT a power supply issue, I power the OAK-FFC-3P externally.

Here is the log after it crashed, but I don't think it is too useful

And here is the log from dmesg, you can see it is correctly showed as SuperSpeed USB device when it is in mode f63b

Some more information about the pi:

Hi erik

Yes, it runs well on my ThinkPad X1 Extreme Gen 4 runs Ubuntu 20.04. I will try the preconfigured image and let you know.

Great, let us know if you still face issues with that image.
