Get list of USB devices connected currently and their dev file in BASH

What is the bash command for开发者_运维百科 detecting all currently connected USB devices and getting the /dev/tty... file that corresponds to the USB device.

Give lsusb a try; for the corresponding file I plug in the device and use dmesg, but there sure is a better way...

This can show all USB devices, including devices that you don't have drivers.

system_profiler SPUSBDataType

Try this:

lsblk -p -S -o  NAME,TRAN  | grep usb

---

dmesg | grep ttyUSB | grep -v grep | grep -o ttyUSB[0-9]
