The following is the text version.
You need to have read and write access to the port (serial, parallel or USB).
Some distributions do not grant read/write access to regular users by default.
Some additional information written by Linus Walleij regarding interaction
between "libusb" and "udev"/"hotplug" is provided here.

For distributions using "hotplug" (Fedora Core 4, Ubuntu 5,...)
The following procedure may be used, to be able to connect to the ICD2/Pickit programmers
as a regular user on those distributions, using hotplug [thanks to Xiaofan Chen]:
* Add the following to /etc/hotplug/usb.usermap:
pickit 0x0003 0x04d8 0x0032 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
pickit2 0x0003 0x04d8 0x0033 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
icd2 0x0003 0x04d8 0x8000 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
icd21 0x0003 0x04d8 0x8001 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
* Add hotplug scripts "pickit", "pickit2", "icd2", "icd21" in /etc/hotplug:
#!/bin/bash
if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
echo "changing ${DEVICE}" >> /tmp/debug-hotplug
chown root "${DEVICE}"
chgrp microchip "${DEVICE}"
chmod 660 "${DEVICE}"
fi
* Create group "microchip" and add your username to this group.
For distributions using "udev" (Debian Sid, Ubuntu 6,7,8,...)
The following procedure may be used to be able to connect to the ICD2/Pickit programmers
as a regular user on distributions using udev [thanks to David Williams]:
* Create file /etc/udev/rules.d/026_microchip.rules:
#PICKit
SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="0032", MODE="0660", GROUP="microchip"
#PICKit2
SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="0033", MODE="0660", GROUP="microchip"
#ICD2
SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="8000", MODE="0660", GROUP="microchip"
#ICD21
SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="8001", MODE="0660", GROUP="microchip"
* Create a group named "microchip" and add your username to this group:
sudo addgroup microchip
(Note: for Arch Linux, it is "groupadd".)
sudo gpasswd -a your_user_name microchip
Similarly for Suse/OpenSuse and Arch Linux and newer version of Ubuntu

For distributions using "PolicyKit" (Fedora 9,10,...)
The following procedure may be used to be able to connect to the ICD2/Pickit programmers
as a regular user on distributions using udev [thanks to Xiaofan Chen]:
* Create file /usr/share/hal/fdi/policy/10osvendor/10-microchip.fdi
http://groups.google.com/group/pickit-devel/browse_thread/thread/86c67b83202815cf?pli=1
* Create a group named "microchip" and add your username to this group.
For distributions using "udev" and PAM (Fedora Core 5/6,...)
The following procedure may be used to be able to connect to the ICD2/Pickit programmers
as a regular user on distribution using udev [thanks to Linus Walleij]:
* Create file /etc/udev/rules.d/026-microchip.rules:
#PICKit
SUBSYSTEM=="usb_device", ACTION=="add", SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="0032", SYMLINK+="pickit1-%k"
#PICKit2
SUBSYSTEM=="usb_device", ACTION=="add", SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="0033", SYMLINK+="pickit2-%k"

SUBSYSTEM=="usb_device", ACTION=="add", SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="8001", SYMLINK+="icd2-%k"
* Create file /etc/security/console.perms.d/pickit2.perms (and similar files for the other devices):
