lsusb - where device description comes from
Solution 1
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.
Solution 2
It comes from the id given through the usbbus from the device.
The description comes from /var/lib/usbutils/usb.ids
.
To get such an information I advise you to simply use man 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 ?
