Port USB qui s'arrête

Bonjour,
J'ai un port USB qui s'arrête de fonctionner quand j'y branche une carte à microcontrôleur MBED : DISCO-F746NG de ST Microelectronics. Plus exactement, le périphérique n'est plus reconnu dans un délai variable après le branchement (quelques secondes à quelques minutes). Le périphérique continu d'être alimenté par le port. La dernière fois j'ai juste eu le temps d'exécuter une fois la commande lsusb :

ubuntu@ubuntu:~$ lsusb
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 003: ID 0483:374b STMicroelectronics ST-LINK/V2.1

Bus 001 Device 002: ID 04f2:b6bf Chicony Electronics Co., Ltd HP HD Camera
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

puis, après la panne :

ubuntu@ubuntu:~$ lsusb
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 04f2:b6bf Chicony Electronics Co., Ltd HP HD Camera
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Quand cette panne surviens, si je branche ensuite un autre périphérique, il n'est pas reconnu jusqu'à ce que je reboot l'ordinateur.

Je suis sous ubuntu 22.04
Si vous avez une idée ?
Marc.

Re : Port USB qui s'arrête

Je viens d'essayer sous une session Ubuntu 22.04 en live usb, le périphérique ne réagit pas, la deuxième ligne ci dessous (Bus 005...) me donne l'impression qu'il manque un driver :

Re : Port USB qui s'arrête

Bonjour,

C'est un port USB3 ?

Re : Port USB qui s'arrête

Merci pour ta réponse,

Oui, c'est un port USB 3 d'après le fabricant de l'ordinateur (HP EliteBook 845G8).

Mais le mode verbeux de lsusb m'indiquerait-il un USB 2 ? :

D'après ton lien, le problème pourrait venir d'un mauvais driver USB (obsolète). Si j'ai bien compris.

Re : Port USB qui s'arrête

Merci pour ta réponse, la carte est alimentée par le port USB.

J'ai un peu progressé dans mes investigations :
J'ai testé la carte avec un live CD d'Ubuntu 22.04 sur un autre ordinateur, cela a fonctionné normalement, sans problème.
Le problème est donc lié au matériel, à voir s'il est possible de changer ou mettre à jour le driver des port USB de mon HP EliteBook 845G8 ?

Marc.

Re : Port USB qui s'arrête

Bonjour , dans ce cas , la 1ere chose a faire est de verifier que ton BIOS est bien a jour .

tu peux aussi tester de passer par un HUB USB autoalimenté , des fois que les ports USB , ne delivre pas suffisament d ' amperage regulier dans le temps .

Re : Port USB qui s'arrête

J'ai démarré mon HP EliteBook 845G8 sous windows 10, la carte branchée sur le port USB fonctionnait normalement et était bien reconnu.
Ça ne viendrait donc pas de l'alimentation USB.
Concernant le BIOS, je suppose que c'est idem.

La différence sans et avec la carte MBED se situe dans les 13 dernières lignes, à partir de [ 2143.828131]...

Ça fait 2 heures que j'ai branché la carte en question et le port USB viens seulement de buger alors que je t'entais de charger un programme dans la carte (j'ai fait 2 chargement de programme sans problème dans ces 2 heures).

suite au bug les lignes suivante se rajoute au autres quand j'exécute la commande sudo dmesg | grep -i usb :
