USBIP server support

On Raspberry Pi2 ubuntu mate 15.10, I did following:

sudo apt-get install usbip
sudo modprobe usbip-core
sudo modprobe usbip-host

Everything went fine, but when I try to start usbip server:

sudo usbipd -D

"usbip err: stub_driver.c: 33 (open_sysfs_stub_driver) usbip_common_mod.ko and usbip.ko must be loaded"

What should I do to fix that? Are such modules really needed? So I have to compile them myself?

This isn't something I've used, but there is a thread that describes this problem at:

Let everyone know whether this is any help.
