SPCP8x5 Driver Installation

About

This is a small howto compile the spcp8x5 kernel driver module. It's used in some ZWave sticks.

Instructions

Installing Subversion

If you don't have Subversion installed do the following:

sudo apt-get install subversion

Get the driver

Check out the driver from the repository:

linuxmce@dcerouter:/tmp$ svn co http://svn.charonmedia.org/svn/vendor/spcp8x5
A    spcp8x5/spcp8x5.c
A    spcp8x5/Makefile
Checked out revision 1512.

Compile the driver

Change into the "spcp8x5" directory and build the kernel driver module:

linuxmce@dcerouter:/tmp/spcp8x5$ make
make -C /lib/modules/2.6.20-15-generic/build M=/tmp/spcp8x5 modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.20-15-generic'
  CC [M]  /tmp/spcp8x5/spcp8x5.o
  Building modules, stage 2.
  MODPOST 1 modules
  CC      /tmp/spcp8x5/spcp8x5.mod.o
  LD [M]  /tmp/spcp8x5/spcp8x5.ko
make[1]: Leaving directory `/usr/src/linux-headers-2.6.20-15-generic
linuxmce@dcerouter:/tmp/spcp8x5$

Load the modules

linuxmce@dcerouter:/tmp/spcp8x5$ sudo modprobe usbserial
linuxmce@dcerouter:/tmp/spcp8x5$ sudo insmod spcp8x5.ko

Verify

Plug the device in and use the "dmesg" command to verify the device initialization:
