SDK 4.0 can't detect camera

Software

1

For some reason, the ZED tools in SDK 4.0.5 cannot detect my ZED camera even though its plugged into a USB 3 port. I’ve attached the output from the ZED_Diagnostic tool below. Under devices, it shows that the camera is in fact detected via USB, and is running on USB 3 (bcdusb=3.0). Everything else in the diagnostic tool checks out fine. Any ideas?

I sometimes run into a detection problem with my ZED2 camera. The main problem I have is the cable. This problem is the same for me for all SKD versions. I contacted support and they confirmed that my camera has a cable problem. Sometimes, the camera is connected and all, but it doesn’t transfer data at the maximum rate it normally does. For example, when I open ZED Explorer, I cannot set the result to HD1080 or 2k. The only thing I do in this case is to move the cable and plug/unplug it until it works. ZED2i has a separate cable, which makes solving this problem easier. If you don’t have a similar situation, then this doesn’t apply to you.
Hope you solve it,

I’ve verified that it’s not the cable, lsusb shows that the connection is at 5000M:

$ lsusb -t
/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 10000M
    |__ Port 3: Dev 4, If 0, Class=Video, Driver=uvcvideo, 5000M
    |__ Port 3: Dev 4, If 1, Class=Video, Driver=uvcvideo, 5000M

Did you end up fixing this by the way? I’m having the same issue
