Determining USB device port

  • 772
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

usb lsusb

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

  2. Or try hwinfo --short Easy to type and remember and you should have enough information to identify your device.
