USB failure with Ubuntu Gutsy

Could not load the Host USB Proxy Service (VERR_FILE_NOT_FOUND). The service might be not installed on the host computer. Result Code: 0x80004005 Component: Host Interface: IHost {81729c26-1aec-46f5-b7c0-cc7364738fdb} Callee: IMachine {31f7169f-14da-4c55-8cb6-a3665186e35e} USB not working (VERR_FILE_NOT_FOUND)

The usbfs support has been disable in the gutsy version by default.

It works well after turning it on in the /etc/init.d/mountdevsubfs.sh file.

/etc/init.d/mountdevsubfs

    #
    # Magic to make /proc/bus/usb work
    #
    #mkdir -p /dev/bus/usb/.usbfs
    #domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
    #ln -s .usbfs/devices /dev/bus/usb/devices
    #mount --rbind /dev/bus/usb /proc/bus/usb

Thanks. That seemed to fix it.

I've found the corresponding changelog entry from the initscripts package I think:

sysvinit (2.86.ds1-14.1ubuntu22) gutsy; urgency=low

• Drop /proc/bus/usb again; software should all be ported to check

/dev/bus/usb first by now.

It appears that virtualbox should check /dev/bus/usb first.

See https://launchpad.net/bugs/151585 for the bug report in Ubuntu.

That's right but even the problem with the missing devices file would persist.

Well, I uncommented them, but still no go. I can now see, without an error my USB devices, and I can add the USB drive from within Virtual Box. Something that I wasn't able to do before. But still nothing...

Running Gutsy Gibbon Ubuntu 7.10 with Win XP as guest.

The /proc/bus/usb interface is deprecated for a long time. This is true not just for Ubuntu, but for even more Linux distros. (https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/151585)

VirtualBox should use the /dev/bus/usb instead.

Replying to sibidiba:

We are aware of this, and it will be done as soon as available developer time permits.

I am facing the same problems with VirtualBox 1.6.0 installed from

virtualbox_1.6.0-30421_Ubuntu_hardy_i386.deb

running on a Kubuntu 8.04 Hardy Heron system.

I have followed the workaround at:

http://www.ubuntu-unleashed.com/2008/04/howto-install-virtualbox-in-hardy-heron.html

and am able to get USB functionality for now.

But I have read that

"Support for /proc/bus/usb has been dropped because it is racey, and permissions are difficult to set -- compared with /dev/bus/usb which is maintained by udev and doesn't have these issues." --Scott James Remnant https://bugs.launchpad.net/virtualbox/+bug/156085

So, when will a workaround be available and how will we know, because the .deb is not part of a Debian archive that can be apt-get at.

Thanks to the developers for a great product.
