Realsense D435 / D455 USB Mode

Rob_NM — Mon, 01 Feb 2021 09:28:43 GMT

Hi everyone,

can one tell me which USB mode the Realsense D435 and D455 are using. Is it Bulk or Isochronous?

Background of this question is that for an Application I have to extend either one of them via Cat and I am wondering whether the extender needs to support Isochronous Mode or not.

The Extenders I am thinking about are:

Thanks

Robert

Thanks @MartyG for replying in the RealSense Forum.

The RealSense Cameras seem to run in Bulk Mode. See here:
