Running multiple cameras on jetson TK1

Hello,
This issue of multiple usb3 cameras on TK1 is widely discussed on the web and here.
quirks = 640/128 , usb_port_owner_info=2 , usbcore.usbfs_memory_mb=1000 , autosuspend …
powering the cameras/hub, changing cameras … none of them solved our similar problem.

it looks like a driver issue, did NVIDIA solve this problems with a firmware/software update ?

Thank you.

Please restart a new topic with current issue you met, also try with latest BSP R21.6.

Thanks
