Hi, is it ok if I use usb-c to usb-c cable instead of the usb-c to usb-3 supplied? Would using USB 4 give any performance boost from eg 4k resolution of OAk-D pro? Would performance still be reduced by cable length if using a USB 3.2 or USB 4 cable?

    Hello glitchyordis ,
    You can use USB-C to USB-C cable as well, just make sure that it's USB3 supported. Regarding USB4 - OAK cameras don't support it, so there wouldn't be any different. And you can also stream 30FPS 4k resolution with USB3, and even with USB2 if 4k frames are encoded πŸ™‚ Thoughts?
    Thanks, Erik

      I'm thinking of upgrading my cable and would like to use the one supplied by Luxonis for OAK-D Pro as a reference.
      May I know the USB version and generation for both ends of the USB cable?

        Hi glitchyordis ,
        It's USB3, gen2 (up to 10gbps) - WRT connector on each side, it depends which cable you were looking at.

          Hi Erik, the document mentions that the recommended cable length should not be > 2 m. Would using an active cable extender such as those below help?


            Hi erik ,

            I've tried to compare latency using the latency measurement code, with resolution set at 12MP.

            Using the cable that came with my OAK-D PRO, I measured the latency on an SS10 and SS port on my desktop. However I noticed that there wasn't much difference in the avg latency, and "getUSbSpeed" returns "super" both USB ports. I expected a lower latency for the SS10 (super speed 10GB USB port).

            I have also switched to another USB 3.2 10GBs cable (Lindy cable), and a similar response was returned.

            Did I misinterpret the results or misunderstood the purpose of the latency measurement code?

              Hello glitchyordis ,
              Sorry about the delay. I think you need to enable usb3 gen2 mode; could you try the following:
              with dai.Device(pipeline, maxUsbSpeed=dai.UsbSpeed.SUPER_PLUS) as device:

              Hello. I was under the impression you need an 8k hdmi cable to watch 4K. I bought one from ebay that said 4K on the front. I hooked it up. But the cable looks the same as my old HDMI. Is there a difference or did I flush $3 down the toilet?

                Hi vawela
                The talk here is about USB, not HDMI; but you need at minimum 2.0 HDMI to stream 4k60 or a USB cable that is C->DP or C that supports thunderbolt 3 or more.

                Thanks,
