I have 32-Bit Vista Ultimate Service Pack 2 and Device Manager shows my 9530 Driver is working properly..
I think Vista Device Manager lets you update device drivers?
Have you Updated Vista Ultimate to SP2?
6 Words that started this whole invention: "Watson! come here I need you!"
Do all the auto updates until you are updated to SP2. Then try reconnecting the device, without the software running. It should bring up a found new hardware and install the appropriate driver. I had the same problem. If not, search google for the driver and just download it. I'd find it for you, but I'm at work, and only the VZW site works here.
You'd be amazed at what you can do with a simple auto update from microsoft.
