Linux Proc Bus Usb
support in VirtualBox in Karmic and before. In Lucid Lynx 10.04, this line is no longer needed, and in fact causes this minor error - though, in some cases, it is actually usbfs rendering the system unbootable. The solution is actually very simple and easy to implement, and merely requires removing or commenting out a line in the fstab file. To do so, open a terminal and enter: sudo gedit /etc/fstab Find the line "none /proc/bus/usb usbfs devgid=125,devmode=664 0 0" and either remove it or add a hash (#) to the beginning of the line to turn it into a harmless comment. If you are in the worst case scenario and can't get to your desktop at all, then at the command-line (which you can get to in Recovery mode) you'll have to open fstab in a CLI-based text editor like nano with the command: sudo nano /etc/fstab (If using nano, Ctrl+X to exit, Y to confirm saving the changes, leaving the file name as "fstab", then press Enter) That's it - your system should now boot fine. ☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻ Did this information make your day?

02/05/2010 - 22:35 Instalación y actualizacionesPues eso he actualizado y cuando entro en la pantalla de inico me sale este mensaje "An error occurred while mounting /proc/bus/usb" y me da la opción de skip o manual recovery". Si le doy a la opción de skip entro normalmente, si le doy a manual recovery entro en modo consola y no se como actuar. Me podeis ayudar a que no me salga ese mensaje y entrar normalmente. Por lo demas todo perfecto. Un saludo.

Alomejor es algo residual que tenemos https://ubuntugenius.wordpress.com/2010/05/07/fix-an-error-occurred-while-mounting-procbususb-bootup-error-after-upgrade-to-lucid/ los que nos hemos actualizado desde versiones anteriores, no lo sé. Sólo sé lo que falta: 1- Abre un terminal (Aplicaciones > accesorios > Terminal) 2- Escribe "sudo nano /etc/fstab" y escribe la contraseña cuando te la pida. 3- Una vez abierto el archivo, localiza la línea "none /proc/bus/usb usbfs devgid=123,devmode=644 0 0", que creo que es la última, y añádele delante una "#". 4- Pulsa "Ctrl" + "X" para salir. 5- Te pedirá que confirmes el guardado, http://www.ubuntu-es.org/node/133153 pulsa "Y". 6- Te pedirá un nombre de archivo, por defecto "fstab", déjalo como está y pulsa "Enter" para terminar. Esa es la solución! :P Si queréis comprobar que funciona, escribid "sudo reboot" para reiniciar, ya veréis como no os vuelve a aparecer el problema. Un saludo y espero que sirva de ayuda. -Alex- (alejandronumerouno) +1 0 -1 Inicie sesión o regístrese para comentar +1 0 -1 Gracias muy amable.

Eso no resuelve el problema. Sirve para evitar que salga el mensaje de error, pero el verdadero problema es que el sistema no consigue montar los dispositivos USB para que puedan ser usados en las máquinas virtuales. El mensaje sólo te advierte de ello para que puedas corregirlo a mano en ese momento. Parece que es un bug del Lucid Lynx. El caso es que no te v

I could not find the usb/devices file in default path, which is: /proc/bus/usb/devices 13.04 usbfs share|improve this question asked Jul 30 '13 at 17:13 Binoy Babu 3211412 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote Not available in the current versions of proc bus usb Ubuntu Usbfs has been deprecated for a long time already. It was disabled since Ubuntu 9.10 (but you could recompile the kernel to get it -- CONFIG_USB_DEVICEFS=y). In the Linux kernel it was completely removed in 3.5 so it is completely missing since Ubuntu 12.10. So the bad news is that you cannot enable usbfs in Ubuntu 13.04 if you do not replace the kernel for an older or patched one. Alternate solution It seems that the similar content as was in /proc/bus/usb/devices is now available in /sys/kernel/debug/usb/devices. Other interesting places to check for the content from former usbfs are: /dev/bus/usb, /sys/bus/usb and /sys/kernel/debug/usb.

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below: sudo mount -t usbfs none /proc/bus/usb -o devmode=0666 share|improve this answer answered Jul 30 '13 at 17:22 Mitch♦ 64.3k12130183 1 Since Ubuntu 9.10 the mount point /proc/bus/usb does not exist because usbfs is not enabled in the kernel. Since Linux kernel 3.5 (Ubuntu 12.10) usbfs is missing completely.
