@"SamiUddin"#p28859 Not if the hub doesn't have it's own power source and if you intend to stream through it. 1. Can't tell if the hub has option to power it separately. 4 devices will brownout your RPI or cause it to shut off the USB port. 2. Max bandwidth is 5Gbps which is enough if you only want to send small streams through. If you want 3 streams for all 4 devices it will become a problem. Thanks, Jaka

That's 15W which is enough for 2 devices (possibly 3). 4th one will likely cause issues - depending on the pipeline.

Thanks,
