lsusb

For one of my attached USB devices (2773:0104) I see no description in lsusb command output:

user@Thinkpad-Laptop:~/binaries$ lsusb
Bus 008 Device 002: ID 0a5c:217f Broadcom Corp. 
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 036: ID 2773:0104

Where USB description is comming from, is it from device driver or is it stored in the hardware itself ?
