I received an Anadigi GPS-206 for Christmas. It came with drivers, and a link in the instructions where other/updated drivers might be found. As nearly as I can tell, the device is functioning fine, but the driver needs the MS Serial Mouse driver to work... (it's a USB->Serial driver). Unfortunately, when I plug the device in, the cursor skips all over the screen, apparently randomly. It happens whether I boot with device plugged in, or as soon as I do plug it in. If I disable the serial mouse driver, the cursor stops jumping. But the GPS stops, too. What with all the fun and games, I can't really be sure the GPS is working properly. the link for the drivers is: http://www.prolific.com.tw/eng/downloads.asp?ID=31 I've been searching the Internet for the past week, and can't find any other drivers - nor even a forum where I might pose the question. So, I'm hoping you can either point me at a decent driver, or even tell me the device is ****. Any definitive answer is a good one. (I'm using Vista 64-bit, build 6002 on a Dell Studio 1735)
