A device installer

I have been having some hard time with a HSDPA/EDGE/GPRS 3G device called Option GlobeSurfer ICON. The driver that comes in the device (works as a regular USB device) doesn't work with Vista. However, the latest drivers provided by Option don't install fine either. As a solution to this, I happened to find working drivers from a Japanese site, the problem being they didn't come with any installer.

This far I've gone through the drivers and selected the INF, CAT and SYS files that do work perfectly under Vista. I've also edited the INF files a bit to make sure they work (using latest drivers files as a base, then fixing information so that they match up with the slightly older but working files: the files are actually a mix between two versions).

The problem I have is that the INF files don't install with the regular rundll/rundll32 method. Even doing a right click on a file and selecting install doesn't start the installation. However I can install some of the drivers via Control Panel's Add Device.


To put my current problems short:

• How can I make the INF files install the drivers?
• How can I disable the USB drive that pops up so that the remaining drivers can install? Afaik this happens by installing a driver to do this, but it doesn't appear in Add Device.

I've attached the files below. I've been using Inno Setup to create the installation, but it of course fails at the moment as I'm using wrong technique to get the drivers installed.


If you're wondering why I'm bothering to do this, the reason is that the manufacturer has had no reaction to fix this issue. Yet this device did come for quite some time for people who ordered HSDPA devices for their Internet use. And now people are switching to Vista, of course having tons of problems with the device as no official set of drivers work directly...



Edit!
Currently working method for installation:

• Unzip files
• Go to Control Panel > Add Device
• Install manually the drivers that can be installed
• Go to Control Panel > Device Manager
• Remove the four devices that were just installed without removing the driver files
• Get the latest official MSI setup and run it
• Everything installs nicely, only thing that needs to be located manually is Flip-Flop Bus (from the unzipped files).

As you can see, this is all too hard for an avarage person to do. However this is the way that ensures the device and connection program works perfectly.
