On my Librem v3 13 running as lsusb produces this output;
$ lsusb Bus 002 Device 004: ID 2001:4a00 D-Link Corp. Bus 002 Device 005: ID 043e:9a21 LG Electronics USA, Inc. Bus 002 Device 002: ID 2109:0813 VIA Labs, Inc.

Because I know our vendor ID I know that the Librem Key line is this one:
Bus 001 Device 015: ID 316d:4c4b
I'll look into what's required for us to have a nice name next to that like other devices do.
