PROBLEMS WITH 10.4 ¶
D-LINK has discontinued the DWL-122. There is no "official" driver for OS X 10.4.
Installing version Driver 1.4.7 will mess up the privileges in your System and break the Spotlight database!
If this has happened to you repair the permissions using the disk-utility and/or
chown -R root:wheel /System/Library/StartupItems and rebuild the Spotlight database by issuing the
sudo mdutil -E / command in ther terminal. After that the Spotlight issue should be fixed.
Still the installed driver is not sucessfully loaded at startup. To solve that try the steps provided here.
If KisMAC should freeze while using a DWL-122, you must unplug it after Force quitting or KisMAC will never fully quit.
