Avec le chemin absolu (désolé pour l’erreur), il ne se passe rien:
le prompt passe à la ligne en dessous, sans rendre la main, et rien ne se passe.
En résumé, il tente des choses mais sans succès.
dmesg à ce moment:

"How do I solve this problem?
The Enhanced Host Controller Interface (EHCI) is a register-level interface that enables a host controller for USB or FireWire hardware to communicate with a host controller driver in software. In this case USB revision 2.0. ehci-hcd.ko is USB 2.0 ‘Enhanced’ Host Controller (EHCI) driver. This error indicates that USB 2.0 may not function on your system, or may function only at USB 1.1 speeds. To fix this problem:
- Replace hardware: In most cases you need to replace the motherboard.
- Remove ehci_hcd driver
- Disable ehci_hcd drive USB 2.0 interface and use it as USB 1.1. In short disable the ehci_hcd."
Qu’en pensez-vous?
