This driver works for the Prolific Technologies Inc USB to Serial cable using Windows XP as well as some of their other products. The drivers that originally came on the CD with the cable were NOT XP compatible, but the driver offered here is. The installation of the file offered here installs a program called PC-Linq for a different product, but the drivers do work if you are just using the USB to Serial cable with Windows XP! (The particular cable mentioned here is labeled with "CE, FCC, Made In Taiwan, 7ST-DH-005"). You can change the COM PORT the cable operates on by going into Control Panel, System, Hardware, Device Manager, Ports(COM and LPT), and right-clicking on Prolific USB-to-COM Port and selecting Properties, then Port Settings, Advanced. I hope this helps! Enjoy!
