From my side, I've been having woes with VBox usb usage, to the point
that I wrote to the developers of VB directly. What follows is the
conversation I had with Mr. Frank Mehnert | Software Development
Director, VirtualBox.

hard to say. I guess if the USB devices worked in the past then this
was probably because the due to the missing Extension Pack the devices
were forced to use the USB 1 mode.

Providing Extenicode for FreeBSD is not impossible but would require
some effort. The most important part is probably to find a compatible
build environment.

I don't say "No" in general but we need to think about this in more

Kind regards,
