USB Converter with Serial speaker connection?

post #1 of 2
Thread Starter 
I have some older logitech speakers that connect to the normal audio output on the computer. However, rather than having a power cord, they have a serial cord also. I was trying to get them to work today, but I couldn't. I go a USB to serial adapter and an adapter to let me plug the speakers serial plug into the adapter (they were both male). I got power to the speakers, but no sound. The speakers are working according to my mom (who was probably using an older computer with a serial plug on the back).

Any ideas?

I'm selling an internal USB -> Serial adapter. Might to the trick.

The issue is, there are all different wiring/controller configurations and you have to find one that'll work correctly for it. Your best bet is to search around for people using the same speakers and see if they list the exact adapter that worked for them, or how somebody else hot-wired it, otherwise you're more or less taking stabs in the dark.
