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 [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-12-15/1702624652-386796-screenshot-from-2023-12-15-01-17-14.png] And here is the log from dmesg, you can see it is correctly showed as SuperSpeed USB device when it is in mode f63b [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-12-15/1702624750-617291-screenshot-from-2023-12-15-01-18-09.png] Some more information about the pi: **release** Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye **kernel** 5\.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux This [link](https://public.3.basecamp.com/p/SXDBt446Pz14wkLaXapEkuSt) has a MRE.

Hi @"lincolnxlw"#1387 , Just to cross out potential OS missconfig, could you try flashing our [preconfigured RPI image](https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/raspberrypi/#using-pre-configured-rpi-os-image)? I'd suggest the V10, which is also 64bit. The camera works as expected on other host computers, right? Thanks, Erik

Application crashed with Raspberry Pi 4 Model B USB 3 port

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.

Hi erik

Good news, I use the precompiled OS V10 and run the same application with the same docker container, and there is no problem with the USB 3 anymore. Now I am able to achieve the FPS I need with raspberry pi!

However, the issue in https://discuss.luxonis.com/d/2623-pipeline-sometimes-not-being-launched-as-expected/6 still persist though.

Thanks

Lincoln
