Ubuntu Gutsy - USB not working

[sensimilla]

After upgrading from Feisty to Gutsy whenever I access the settings or start a machine I get the following error:

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:

Callee:
IMachine {31f7169f-14da-4c55-8cb6-a3665186e35e}

I have tried 1.50 and 1.52 same result.
I have edited the /etc/udev/rules.d/40-permissions.rules to change group ownership of usb devices as reccomended here:
http://www.virtualbox.org/wiki/USB_on_Ubuntu_7.04
All was working well under Feisty.

Anybody got any ideas how to fix this ?

I have the exact same problem. Hopefully there is a solution out there somewhere.

Ubuntu removes usbfs in Gutsy. We rely on that for USB, so currently there's no easy solution. Perhaps you can compile it back into the kernel.

OpenSuse once tried the same thing until they realized it was a very bad idea. (it also breaks VMWare)

Ok, think I may have found the answer here:

http://www.virtualbox.org/ticket/747

I'll reproduce it here.

You need to edit an init script:

Code: Select all   Expand viewCollapse view

sudo gedit /etc/init.d/mountdevsubfs.sh

Then look for the following:

Code: Select all   Expand viewCollapse view

    #
    # 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

Remove the #'s from the last four lines so it looks like this :

Code: Select all   Expand viewCollapse view

    #
    # 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


Reboot

This seems to have fixed the issue for me.

Works for me, too! Thanks for the tip!

btw - a /etc/init.d/mountdevsubfs.sh start works for me

This fix SORT OF worked for me. Now I can see usb under "settings" but when I start xp all of the usb devices are grayed out. Not sure what that problem is but we are making headway. Any ideas?

[grahams1]

thanks, this worked for me also.

tip for getting xp to see the usb devices. The 1st time I enable a usb device
Device > USB Device, my XP guest saw the device but them failed to install. I disable the device in VB and then re-enabled and Xp them saw it correctly.

same problem:

Code: Select all   Expand viewCollapse view

Not permitted to open the USB device, check usbfs options.

I think you have to follow the procedure described here for 7.04 to change the usb filesystem permissions.

http://virtualbox.org/wiki/USB_on_Ubuntu_7.04

I'll quote it here for convenience

After I had a taken a look into the insides of Ubuntu 7.04, I managed to get VirtualBox's USB-Support working there in such a way that the user only needs to be a member of a group called usbusers. This howto describes how I did it.

Basically, you just have to tell Ubuntu that a group called usbusers should have read and write access to all usb devices.

1. Create a group called usbusers

2. Add yourself to this group

3. Edit the file /etc/udev/rules.d/40-permissions.rules (for this, you must have administrative privileges)

3.1 Search for the following lines

Code: Select all   Expand viewCollapse view

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device",                    MODE="0664"

3.2 Change them to the following

Code: Select all   Expand viewCollapse view

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", GROUP="usbusers", MODE="0664"

4. Restart your PC

5. You should now have write access to all usb devices.

I fix the problem with the USB:

first i use the code of the first post of this thread;

then i use the code of this site:

http://danieleparlante.wordpress.com/2007/07/30/risolvere-i-problemi-tra-virtualbox-e-lusb/

and now the USBs works perfectly!

I hope this will help.

Bye

Sorry, but I was having difficulty trying to sort out the fix posted by matthew_eli. I AM NOT bilingual. Can someone point me to the fix in English?

[rcdeacon]

OK, just for the record I finally got usb working! The trick for me was to make a new group called "usbusers" as someone posted. Thanks for steering me in the right direction.

1. Create a group called usbusers

2. Add yourself to this group

3. Edit the file /etc/udev/rules.d/40-permissions.rules (for this, you must have administrative privileges)

3.1 Search for the following lines

Code: Select all   Expand viewCollapse view

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device",                    MODE="0664"

3.2 Change them to the following

Code: Select all   Expand viewCollapse view

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", GROUP="usbusers", MODE="0664"

4. Restart your PC

5. You should now have write access to all usb devices.

Instead of creating a group called usbusers. I just used my user name. That worked for me. I'm using Mint 3.1 Celena.

Thanks, this was helpful to me as well.

This is a really easy fix

or just add this line to /etc/fstab

none /proc/bus/usb usbfs devgid=1002,devmode=664 0 0

the devgid number is the vboxusers group id (check to see if yours is different)

Once you've saved and closed fstab just do a sudo mount -a and you should be good to go.
