Most NVR's have USB port for thumb drive to transfer data to drive.
Thanks for your cooperation
How do I transfer files via a USB port? How do I specify the USB port path, and what commands are available to use? What commands can I use to transfer?
Knowing that I tried to use some commands to specify the USB path, such as:
View USB devices
lsusb
lsblk
But they all failed
Excuse me, I have very little knowledge of Linux. Would you please help!
