I was doing tests with a Unity project that uses the camera. After some usual tests the camera stopped booting up when the test started. Have you experienced something similar? I didn’t turn off the computer or anything; after that i reinstaled the SDK and drivers but not event ZED explorer or ZEDfu could use the ZED cam. Restarted computer and all. Im trying on a different computer to see if something works; also reinstales USB drivers but didn’t help. I read it could be something about the voltaje of the USB interface; I tried changing it and using different USB C cables; but nothing helped.
There’s guidelines saying that a usb-port has to be 3.0 or greater → this can be determined by the allowed bandwidth I think. Aside from that I’m also experiencing issues 
I confirmed i tried on a USB 3 :0 but no luck
Ahhh that sucks I’m sorry - I’m trying to look into this issue as well; I’ve tried using the 5.1.2 sdk version with CUDA 13.1 which at least lets me use zed explorer but beyond that none of the other tools really work. Would you be open to hop in a call to figure it out together
