optional but recommended PWCX module installation
NOTE: You must be the root user to do this. 

To update (or install) the PWCX kernel module, place the PWCX 8.2.2 tarball into the /var/tmp directory and untar the PWC module tarball in a clean temporary directory: 

mkdir /var/tmp/pwcx
cd /var/tmp/pwcx
tar -zxvf /var/tmp/pwcx-8.2.2.tar.gz

Now copy the pwcx-i386.o file into the hotplug usb sub-directory: 

cd /var/tmp/pwcx
mkdir -p /etc/hotplug/usb
cp -p pwcx-i386.o /etc/hotplug/usb

NOTE: If you are running on a PowerPC system, then you want to copy pwcx-ppc.o instead of pwcx-i386.o
