Windows 7: Prolific USB-To-Serial Driver

Which one did you install? Did you install the PL-2303 Vista Driver Installer? I'm wondering if you have the same hardware that I have - my device shows up as Prolific USB-to-Serial Comm Port.

I guess you could uninstall again, reboot, and install in XP SP3 compatibility mode. It's worth a shot. I did so much installing/uninstalling that I honestly don't remember exactly how I got it working. But I do know that it was the driver I gave you and not one I downloaded.

Looks the same to me. Maybe your virtual serial ports are preventing the USB-DB9 driver from functioning. But first - uninstall and try it in XP SP3 compatibility mode. If that doesn't work, can you uninstall the virtual serial ports to see if that helps?

Also - update your system specs (lower left corner of your post).

Ok I tried to do the XP Sp3 compatibility thing, but the driver itself stopped me from doing that. It said it was only vista compatible. One driver that I tried to install with this device gave me the Prolific usb-to-serial name, but I don't know which driver that was. Seems like this isn't going to work :-(

Do you want to uninstall your virtual serial ports and then try installing in Vista mode?

Yea, I tried that as well.. I removed both the RIM virtual serial ports for my blackberry and still nothing. I don't want to give up on this because I need it working before Tuesday.

If you uninstall the driver, reboot, and then plug in the adapter, does it install or does it report missing drivers?
