Determining USB device port
lsusb | grep UART
returns:
Bus 001 Device 006: ID 10c4:ea60 Cygnal Integrated Products, Inc.
CP210x UART Bridge / myAVR mySmartUSB light
How can I confirm that the device is at: /dev/ttyUSB0
without unplugging the USB device?
ls /dev/tty* | grep USB
returns /dev/ttyUSB0
only when the device is plugged in, which seems to confirm the USB port location. I am seeking a confirmation process does not involve unplugging the USB device.
Update:
the USB device is not a disk: it is a ESP32 microcontroller

In a terminal, type this command: udevadm info --name=/dev/ttyUSB0 --attribute-walk
You should have enough information to identify your device.
