I have a setup here with a lot of USB devices connected this is my lsusb output:

as you can see there are multiple of the same devices and multiple hubs with the same vendor id and all. I am monitoring these with Wireshark (tshark actually) and I get some errors like this:

293549  43.514117       3.17.1 → host         USB 66 URB_BULK in[Malformed Packet]

However, I can't physically identify which device it is without the device's serial number.

I can see this serial number on dmesg

[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: New USB device found, idVendor=16c0, idProduct=05dc
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: Product: USB BDC
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: Manufacturer: www.engineeredarts.co.uk
[Wed Feb 17 16:03:29 2021] usb 1-3.2.1: SerialNumber: 345B34673238

My question is: How can I match these two things? or at least, how can I get that same 'SerialNumber' that dmesg displays, of the numbers I get from tshark?

(resetting each device to see which one is which while watching dmesg and lsusb isn't an option)

Got it! Turns out you can see the serial with sudo lsusb -v. It has to be run as root otherwise the files will be empty, then to clean all the useless info did a quick grep like so:

lsusb -v | grep '^Bus\|iSerial'

This is grepping 2 results (separated by \| which is the OR operator), first one are stuff that start(^) with the word Bus and the second one is that it contains the word serial

also stumbled across another command that I didn't know about:

usb-devices
