Not sure, I don’t know this camera, but if it supports MJPG you may check this:

Failed to allocate memory for four usb cameras

Hi @bryanmok, If you need to use 4 usb cameras without changing to usb 3.0, you can use a workaround to “hack” the uvc-video driver. Find instructions in the following guide: Installation_Guide#Patch_to_support_4_USB_cameras Please notice probably the patch will not apply directly, but you can manually add the lines at the driver source file. Regards, Fabian

For other formats, even less sure but you may try other uvc driver quirks for bandwidth.
