usdm_drv problems

Hi, when I follow the tutorial to install the software, I meet with problems below. Maybe at the end of the procedure of make install

Starting QAT service
modprobe: ERROR: could not insert 'usdm_drv': Unknown symbol in module, or unknown parameter (see dmesg)
Restarting all devices.
Failed to stop device
Checking status of all devices.
There is 0 QAT acceleration device(s) in the system:

*** Error:usdm_drv module not installed ***

make[1]: Nothing to be done for `install-data-am'.
make[1]: Leaving directory `/home/lx/QAT'

any pointers much appreciated.
