Intrepid/Virtualbox/USB

[txHarleyMan]

All,

Has anyone been able to get USB working with Virtualbox 2.0.2 ( non ose version ) ? I'm running Intrepid Beta.

Yea I have it working in mine. I forget the link to the source I used to set it up though, Ill look for it and post back here if I find it.

As usual make sure you have added yourself to the vboxusers group.

Also I checked my fstab so I know I had to add this to get it to enable on every boot:

#usbfs
none /proc/bus/usb usbfs devgid=46,devmode=664 0 0

Ill look for that article to see if I changed anything else because I dont remember off the top of my head since the process was different from the way it was done on Hardy.

Thanks, JU. I didn't add anything to my fstab. Will try after work today!

Here you go:

It mentions Hardy but worked out for me.

Setup VirtualBox USB Support: USB is disabled by default, so you'll probably want to enable it. Otherwise you'll get an error when you go into the "Settings" of your virtual machine. To correct this, you'll need to edit the mountdevsubfs.sh file: sudo gedit /etc/init.d/mountdevsubfs.sh You'll see a block of code that looks like this: # # 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 Now uncomment the last 4 lines above to look like this: # # 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 Ok now logoff, then log back in so the vbox driver see's you are logged in to the vboxusers group. If the above doesnt work try rebooting, if that doesnt enable usb you can try this: Grab the vboxusers group id: grep vbox /etc/group vboxusers:124:ionstorm Edit the fstab with the group id # in bold: sudo gedit /etc/fstab Append this to the fstab then save/exit: ## usbfs is the USB group in fstab file: none /proc/bus/usb usbfs devgid=124,devmode=664 0 0 Now lets edit the mountkernfs.sh file with the gid in bold: sudo gedit /etc/init.d/mountkernfs.sh Paste the 2 lines below above the line: "# Mount spufs, if Cell Broadband processor is detected" ## Mount the usbfs for use with Virtual Box domount usbfs usbdevfs /proc/bus/usb -onoexec,nosuid,nodev,devgid=124,devmode=664 You may not need to reboot, try doing: sudo /etc/init.d/mountkernfs.sh If not, reboot, and virtualbox should detect your usb devices!

Regarding the part of 'magic' in mountdevsubfs.sh, you can compare with mine if it is not in your file:

}

case "$1" in

This doesn't work in intrepid due to the changes. You must add the information to fstab. Its alot easier to do imo: )

Correct. Working fine now. Thanks, All!

This worked like a charm for me in Intrepid. Thanks!

[davidfg4]

This did not work for me.
I made sure I am in the vboxusers group, added the line from ju2wheels's post to my fstab, and restarted.
I also tried having devmode=666 and devgid=124 (the id of the vboxusers group).
No matter what I tried nothing ever showed up in the Devices > USB Devices menu.
I am on Intrepid and using virtualbox 2.0.2_OSE.
Any ideas as to what I am missing?

David

EDIT: It looks like the OSE edition does not support usb, I will get the non OSE version.

[davidfg4]

Alright, I got it working!
Thanks everyone!

Wow, I didn't know the solution would be so simple. I never really had to use USB in a VM, but the warning box was always a bit unsettling =p

It's easier than the Hardy fix.
