I'm running the newest version of VirtualBox, 4.1.18-78361~Ubuntu~precise from the VirtualBox repository, on Ubuntu 12.04 with the Oracle VM VirtualBox Extension Pack.
When I go into Settings->USB for my virtual machine and click "Add Filter From Device" I get no devices in the list. Only a text saying "no devices available".
The device I'm trying to use in the Windows 7 x64 guest OS is a SATA-to-USB controller that is present on my Ubuntu system. There is both this device and USB mouse connected to my Ubuntu PC, neither of which show up in VirtualBox (output from lsusb):
Bus 006 Device 002: ID 046d:c050 Logitech, Inc. RX 250 Optical Mouse
Bus 003 Device 002: ID 174c:55aa ASMedia Technology Inc
I've set up a USB device filter on the Settings->USB page for a device with Vendor ID 174c and Product ID 55aa. When I plug in the device, however, a prompt from Ubuntu pops up asking me to enter the password to decrypt the volume (the disk in the SATA-to-USB controller is encrypted using dmcrypt and set up with LUKS).
My user is a member of vboxusers:
rune@rune-desktop:~$ groups rune
rune : rune adm cdrom sudo dip plugdev lpadmin sambashare vboxusers samba
How do I get my Ubuntu 12.04 host OS to pass on the USB device to my Windows 7 guest OS?
EDIT: Output of ls -lR /dev/vboxusb/
as requested:
/dev/vboxusb/:

EDIT: Now it works :. I have no idea what I did (if anything) to make it work. But now all the devices show up, and the guest OS can use the device in question correctly.
ls -lR /dev/vboxusb/
