cannot map USB storage to VM from OS X

[Bayard Bell]

I've been trying to get a USB mass storage device mapped to an OpenBSD guest, and I've not been having any success mapping the device to OpenBSD, Ubuntu, or OpenSolaris. If I select the device from the USB pop-up, I immediately get the message "Failed to attach the USB device 0000:0000 to the virtual machine". After this, no USB devices show up as available for attachment to the VM, and the mouse integration pop-ups are displayed whenever I recapture the display, refusing to acknowledge that I've checked the box for "Do not show this message again", which I had in any checked previously.

I'm attaching the Ubuntu VM logs, as this is a fully supported OS.
