Hi,
I am using zed 2i to capture images.While I am always get a information that Unable to capture images, Consider trying a lower resolution and/or FPS. I try to check my USB port and as follow:
Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/5p, 20000M/x2
|__ Port 1: Dev 116, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 4: Dev 117, If 1, Class=CDC Data, Driver=cdc_ncm, 5000M
|__ Port 4: Dev 117, If 0, Class=Communications, Driver=cdc_ncm, 5000M
|__ Port 4: Dev 3, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 5: Dev 126, If 0, Class=Video, Driver=uvcvideo, 5000M
|__ Port 5: Dev 126, If 1, Class=Video, Driver=uvcvideo, 5000M
This means ZED 2i usb port is a 3.0. But why the error was captured and thus failed to open camera. The detail err as follow. Help!!!
