Everything is working except USB

Bill Roberts · Post by **Bill Roberts** » 14. Sep 2008, 22:00

In the Settings I can set my USB devices and I have 3 active filters that appear correct.

In the VM under machine - USB, the popup list shows all of the usb devices on my pc, but all have status Unavailable and are greyed out.

I've set fstab according to the other topics about this issue.

My usb devices work correctly on the host (Hardy)

Any suggestions?

Did you also do the other options other than the fstab entry? And did you run that properly? See the VirtualBox FAQ for some help. There is also a link to the Wiki FAQ that describes USB in Ubuntu (you can also find this in the Help documentation of Ubuntu.com and other sites).

First, I'm not new to computing...

Yes, I have installed the PUEL Edition, so USB support should be available. I have read the Wiki and followed all of the steps there.

I used to run the VMware server and it worked with the fstab entries I made for that.

Here's my VirtualBox fstab entry:

/sys/bus/usb/drivers /proc/bus/usb usbfs devgid=131,devmode=664 0 0

131 is the correct devgid.

Please look into the FAQ. On Ubuntu there is more to do.

Code: Select all

none                            /proc/bus/usb   usbfs   devgid=505,devmode=664          0       0

That is my line for /etc/fstab and working. You don't need a mount point.

Thank you - can you please supply a link? The FAQ on this forum doesn't mention ubuntu and the Manual doesn't specify any special needs for ubuntu USB support.

Found this for ubuntu/Gutsy:

/etc/init.d/mountdevsubfs.sh start

I'm on Hardy but I did it anyway, now I'm getting

Failed to create a proxy device for the USB device. (Error:VERR_FILE_NOT_FOUND)

which I hope is referenced elsewhere on this forum.

Finally found the problem...

If you have done all the steps called for in the various FACs and it still doesn't work then

REBOOT the host machine.

You always have to reboot when changing system specific files. If you would have followed the link at the end of the FAQ to the Wiki FAQ, you would have seen the Ubuntu USB part. There will be some changes here and there when the new forum software is up to avoid these things.

Why do you assume I didn't follow those links? The FAC specifically says ubuntu/Gutsy and I run ubuntu/Hardy. I only got the connection by visiting other sources.
