pwc hotplug script installation
NOTE: You must be the root user to do this. 

We are now ready to install the pwc hotplug script. 

Create the pwc hotplug script: 

cd /etc/hotplug/usb
cat >pwc <<EOF
#!/bin/bash
#
# Phillips webcam module setup
#
# See: www.smcc.demon.nl/webcam/support.html for support or

/usr/bin/logger -p daemon.notice -t hotplug/usb/pwc -i Phillips webcam setup
# place any pwc options such as size=vga fps=15 on the end of the next line
/sbin/modprobe pwc
# optional PWCX module
if [ -f /etc/hotplug/usb/pwcx-i386.o ]; then
    /usr/bin/logger -p daemon.notice -t hotplug/usb/pwc -i pwcx-i386.o insmod
    /sbin/insmod --force /etc/hotplug/usb/pwcx-i386.o >/dev/null 2>&1
fi
/usr/bin/logger -p daemon.notice -t hotplug/usb/pwc -i Phillips webcam complete
EOF
chmod 0555 /etc/hotplug/usb/pwc

NOTE: If you want to change the default PWC module parameters then add them onto the /sbin/modprobe pwc line. For example: 

/sbin/modprobe pwc size=vga power_save=1 \
	fps=15 leds=250,750
