[usbip-devel] Adding usbip modules problem.

[Trần T. T. <gi...@gm...>]

Hi all,
Sorry for posting here, but I can't find anywhere to ask.
I have RHEL 6 with
# uname -r
2.6.32-131.0.15.el6.x86_64

I'm trying to build usbip modules on staging driver. Everything is OK. I
have all needed *.ko files.
But I cannot add those modules on running kernel.

# pwd
/lib/modules/2.6.32-131.0.15.el6.x86_64
# ls | grep ko
usbip_common_mod.ko
usbip.ko
vhci-hcd.ko

# modprobe usbip
FATAL: Error inserting usbip
(/lib/modules/2.6.32-131.0.15.el6.x86_64/usbip.ko): Required key not
available
# insmod usbip.ko
insmod: error inserting 'usbip.ko': -1 Required key not available

How can I add it? Do I need to rebuild whole kernel?

TIA,
giobuon
