Serial to USB trouble (DexDrive)

I have a serial device (DexDrive) that I want to connect to my computer which, unfortunately, does not have such a port. Thinking myself clever, I purchased a serial-usb adapter.
(This is the same one if you care to look: hxxp://cgi.ebay.com/USB-2-0-TO-RS232-SERIAL-DB9-9-PIN-ADAPTER-CABLE-PDA-GPS_W0QQitemZ380077197849QQcmdZViewItemQQptZCOMP_EN_Cables_Connectors?hash=item380077197849&_trksid=p3286.c0.m14&_trkparms=72%3A1234|66%3A2|65%3A12|39%3A1|240%3A1308)

Of course the application wants to look for the device over a com port and will not detect the device, even though it is connected.

I have seen one solution that's a couple years old. Unfortunately it's also a bit vague (hxxp://www.atariage.com/forums/index.php?showtopic=124686) That's the only lead I have so far though.

What I'm basically saying is that I need to connect a serial device through the usb port so that the application can read from and write to it.

Does anyone know any solutions or hints for this?

 

When you plug it in do you see a com port in your device list?
MAybe you need to change its properities to COM 1 or 2 so the dex drive will be seen.

 

If it comes down to it, I may just have to purchase a different piece of equipment. I'd like to see if there's any way to work with what I have first.

Change the properties to COM? I haven't stumbled upon that just yet. How would I accomplish that?

Thanks for the feedback.


note: I put up a couple screen shots of what I believe to be the system trying to recognize the device.
In all honesty, I think I may have to cough up the cash for a non-generic adapter or a pci card. (I think I still have a slot open ;p)
