I have the F5U103v. That is a USB-to-serial adapter too. If you use "Everest home or corporate" software and connect your hardware, although you have a driver error, Everest will indicate to you (in devices/USB devices) the true hardware manufacturer. In this case "Prolific Technology Inc." and not "Belkin".
There is a link for my case and probably yours, but if it doesn't run, use Everest to locate the real manufacturer:
http://www.prolific.com.tw/eng/Download-2.asp?ID=17
And click on "PL-2303 USB to Serial Bridge Controller" /software and drivers. There is support for all Windows OSes, 32 and 64-bit, Windows 7 included.
This same link could help Mac users. Click on "User Manual" for Linux users.
(The "PL-2303" reference is the hardware ID that is located in "Device properties/ Device ID" on Everest software).
Always use this software for locate drivers for your new hardware devices.
Update: The site is now down, but through google cache you can still reach the downloads. Direct links: google cache

Belkin USB to Serial Not Working on 64bit OS
Belkin did not make 64 bit drivers for this part. Purchase newer USB to Serial adapter (Moxa UPort 1100) Use the drivers from another USB to Serial adapter that has the same chipset, one that does support 64 bit.

If your trying Windows 7 or Vista 64bit, you'll find Belkin don't have 64bit drivers. However, Belkin don't make the drivers anyway. You can checkout this blog post on how to get it working under 64bit Windows: http://www.clearchain.com/blog/posts/how-to-use-a-belkin-f5u409f5u409-cu-usb-to-pda-serial-converter-in-visawindows-7-64bit-mac-osx-10

For anyone running across this thread as a search result, don't try to follow the link to "www.mct-us.com," as you will get a 404 error. Magic Control Technology (of Taiwan) has apparently discontinued the "MCT-US" website.
