I found this advice on another site:
"You will need to install drivers for your usb serial adapter, A good way to find which drivers to install (if u dont have them) is to click the apple Icon on the top left, 'about this mac'then click the 'More Info' on the window which appears, then look for USB devices.
Your serial adapter should appear as a usb device, THen google for the os x usb drivers for the chipset/adapter, or contact your vendor/look on sourceforge for it."
I don't know if that's the problem, but you should have gotten a driver disc with the converter cable. The one I just received for a pc client has a CD that says it's for Windows and Mac.
One problem though, the disc is a mini-cd. Not great for slot loading drives, and the driver says Mac 10.1 - 10.3.3. Maybe that's when they made the cable, but I wouldn't be very surprised if it didn't work with Leopard. It's going on a PC so I won't have to worry about it for now.
Side note about these cables - I have another client who wanted to control his ham radio gear from a Mac running WinXP on Parallels. It wouldn't work in WinXP until I removed the driver from the Mac side. Windows kept complaining that the device was already under control by another program - it meant Mac OS. I'm not sure how I would have been able to make the device work both ways, but luckily, didn't have to find out.
Leopard saw his Radio Shack cable fine from System Profiler.
