Belkin f5u409 driver

I need the driver for the cable to install it on my laptop which has vista. I already tried the belkin website but that was a waste of time. Do you know of a beta version? or anyother solution?

    I downloaded this driver, (Belkin product) and it does not work on Vista 64 bit.

    However, I did find new adapters at several sites on the net that have the Vista 32 AND 64 bit drivers on the disk. Will probably try that route next.

    The problem I am currently having (have not bought the new adapter yet) is "serial port is engaged" when I try to do the data transfer. Windows keeps telling the driver is not installed, even though it is.

Found a driver at Register with the site, search for f5u409 and the third one down I think is the Vista driver. Hopefully should solve your problem.

Windows vista home premium can't recognize product and won't installI am using F5 theU257 v1 thethe compatible 32 bit for my 64 bit machine. Please Help. Thank You.

Download the appropriate Windows 7 driver from here:

Use the 64 bit one if you have a 64 bit OS, and a 32 bit one if you use a 32-bit OS.

Or you can download both, start with the 64 bit one. If it is not compatible, the installer will complain and abort.
