rated 0 times [ 8] [ 0] / answers: 1 / hits: 7181 / 3 Years ago, thu, may 13, 2021, 12:47:49

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 ?

The device identifies itself only with the ID value. This is made up with a 2-byte code (4 hex digits) identifying the manufacturer (eg, 0a5c for Broadcom), followed by a 2-byte product identity (217f).

Ubuntu uses the database maintained here. If you have a piece of hardware not identified by the current version of this file, you could tell them about it. The manufacturer ID 2773 currently has no entry.
