Voici quelques commandes, explications et exemples pour identifier précisément un device USB sous GNU/Linux.
lsusb permet de lister ce qui est connecté sur les ports USB d'une machine.
$ lsusb Bus 002 Device 004: ID 04b3:310c IBM Corp. Wheel Mouse Bus 002 Device 005: ID 1038:1202 Ideazon, Inc. Bus 002 Device 003: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 004: ID 0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
On peut préciser différentes choses, afficher les résultat pour un seul device
# lsusb -s 001:002 Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Avec l'option -v (verbose), on obtient beaucoup de détails !
# lsusb -v -s 001:005 (... plein de détails! ...)
On peut voir pas mal de choses via dmesg.
Combinaison de watch, dmesg et tail :
