Get serial numbers of connected USB devices
Information about USB Devices is stored differently under Linux then macOS:


In Linux, usb-devices is a bash script that essentially reads a bunch of text files, symlinked to /sys/bus/usb/devices/usb*, that contain information about the USB Devices and formats it in the output you see under Linux.
In macOS, it does not have such a script as it doesn't store the information in the same manner. However, if you want to output information about USB Devices that are enumerated by the OS, in Terminal, then use the following command:

system_profiler SPUSBDataType


If a USB Device has a serial number it will be shown in the output.




As mentioned by Allan in his comment, you can use the following command to minimize the output to include relevant portions of the device information that contain the device name and serial number with a bit of additional info.

system_profiler SPUSBDataType | grep "Serial Number" -B5


Note that doing this does obscure some of the device information as compared to the info outputted by usb-devices, although it may be unnecessary info depending on your needs.



As an example, here is the usb-devices output, in Linux, for an 8 GB USB Flash Drive:

T:  Bus=03 Lev=02 Prnt=03 Port=00 Cnt=01 Dev#=  6 Spd=480 MxCh= 0

S:  Manufacturer=SanDisk
