Starfish,
For Windows ME and Windows 98SE backlight problem, I would suggest you to try a clean installation and using the driver set from the following FTP server. You should find two ZIP files for WinMe and Win98SE. They contain video, modem, sound, AGP that I am currently using, and it should work. If not, please let me know. BrianChen@Weirdness.com

I am too experienced problem with the Dlink USB Adapter(650). I first notice the problem when I was trying to send JPG flies to the i-opener for web server. The file became currupted after the transfer. After several test, I have conculde that the curruption occur in both transmit and receive, and the only reliable way to transmit anything over the DLink 650 is by setting FTP server on one of the computers.
In addition, I also notice that the problem occur randomly. However, transmiting a very large file (<100MB) will more likely make it happan.
FIY, I am only running TCP/IP on the i-opener. I have tried both NetBEUI and IPX/SPX, and they are both so unliable on the Dlink 650 that it can't even mainten a reliable connection to transmit anything over 10MB.
