Adding to that; after you've found the device, you can then use the
verbose mode to show you more info on the device itself. Example:

$ lsusb
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 002: ID 09da:0006 A4 Tech Co., Ltd Optical Mouse WOP-35 /
Trust 450L Optical Mouse
Bus 001 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000

So I want to see the added info on the mouse (Bus 001 Device 002: ID
09da:0006), so I ask for the verbose output of the device on Bus 002:

~$ lsusb -s 002 -v
