VirtualBox Can't Find USB Devices

Question

Hi all,
Just run into a USB issue in VirtualBox, I tried everything I can find on internet, but nothing fixes it.
It used to work fine before, I don't know when was it broken. Here's some information:
I'm running VirtualBox 4.2.6 on Linux 3.6.11-1-ARCH.
I added myself to vboxusers, and I have
export VBOX_USB=usbfs
in ~/.xinitrc
I also have VirtualBox extension pack installed.
Now the weird part is, I can access USB devices if I run VirtualBox with root privilege, while with my own account, it shows the following error message once I click "Settings" button:
Failed to access USB subsystem.
Could not load the Host USB Proxy service: VERR_NOT_FOUND.
Anyone has any idea what's going on?

Answer 1

Guys.
Was there a solution found?
I get the same error on current (fully updated) install.

I tried the repo version, now I have installed AUR version. No go.

I was rebooting many times today.
I have tried adding this:
VBOX_USB=usbfs
and this:
export VBOX_USB=usbfs
to the
~/.bashrc
Found this page and I see these two commands:
VBoxManage list usbhost
ls -lR /dev/vboxusb
The results are:
Terminal wrote:
[andrzejl@wishmacer ~]$ VBoxManage list usbhost
Host USB Devices:
<none>
[andrzejl@wishmacer ~]$ ls -lR /dev/vboxusb
ls: cannot access /dev/vboxusb: No such file or directory
[andrzejl@wishmacer ~]$
Then I have found another page which said:
Some other page wrote:
Add this:
usbfs /proc/bus/usb usbfs defaults,devmode=666 0 0
to the
/etc/fstab
and reboot...
BUT I double checked before adding it...
Terminal wrote:[root@wishmacer andrzejl]# ls /proc/bus/usb
ls: cannot access /proc/bus/usb: No such file or directory
[root@wishmacer andrzejl]#
SO... There is no such folder - the mount would fail...
Here I can see the info:
Page linked above wrote:

/proc/bus/usb is removed from kernel 3.5.0. That is the problem?
Basically I have spent the last 3 or 4 hours (maybe more) trying to figure this out on my own - I thought it would be a good idea to report this here as this thread is similar (to say the least) to my case and then keep searching for a solution to this annoyance.
Regards.
