Found a Fix for the Prolific chiped DCAB-N320U DKU-5 USB Data Cable -
Nokia that does not connect with Nokia PC Suit. -

The original recommended driver Version 1.10 - Is Junk!
down loaded driver is faulty - Nokia Phone suit will not connect.

The Software driver that works is from Prolific Tiawans Web site that
works real well link shown:

PL-2303H/X/HX Installshield Driver Setup Program v2.0.0.14 for
Win98SE/ME v2.0.0.26 for Win2K/XP (XP Logo Certified) for Prolific USB
VID/PID Only 2004-08-31 15:43:54 1,479,5772138

Hope this helps.
