Have anyone tested a USB to RS232 adapter? If it so, what brand?

Edit:
I found a driver for usb to serial adapters, but no of the adapters I can get ahold of here is listed:
http://sourceforge.net/projects/osx-pl2303/

The ones I can chose between: Deltaco and Sweex. Has anyone tried one of these?

Hello, I brought a cable USB to RS232 and i instaled the software of the CD that came with the cable.. But i think the Hackintosh doesnt Load the kext, i think thats the problem... My cable is a Konig Computer cable brand...
