See below, I suspect you have a resource clash. Option 2 below should work for you.
PROBLEM DESCRIPTION:
The Merlin is installed as a multifunction device. It occupies one device location on its bus, but has more than one function. Each function is associated with a driver that will service that operation.
Installation of the Merlin will fail if one of the functions is not properly initialized. Windows Device Manager will display an error with either the Modem or Port device. Error code 10 appears in the properties of the problem device, indicated by an exclamation mark.
To view this, follow steps below.
1. Insert the Merlin into the PC card slot.
2. Go to Device Manager. Start > Control Panel > System > Hardware > Device Manager.
3. Expand the Modems, the Multifunction adapters and the Ports category.
CAUSE:
This problem occurs because Windows resource allocation is not properly achieved.
SOLUTION:
There are three possible solutions:
First, perform an update driver, from Device Manager just incase during the initial installation
Windows did not install the drivers properly.
1. Insert the Merlin into the PC card slot.
2. Go to Device Manager. Start > Control Panel > System > Hardware > Device Manager.
3. Expand the Modems, Multifunction adapters and Ports category.
4. Select the Novatel Wireless UMTS Modem Parent under the Multifunction adapters category.
5. Right click and choose update driver from the available menu.
6. Choose install the software automatically (recommended) from Windows Hardware Wizard.
The second solution is to manually assign resources to the Parent device
1. Insert the Merlin into the PC card slot.
2. Go to Device Manager. Start > Control Panel > System > Hardware > Device Manager.
3. Expand the Modems, the Multifunction adapters and the Ports category.
4. Select the Novatel Wireless UMTS Modem Parent under the Multifunction adapters category.
5. Right click and choose properties from the available menu.
6. Choose the resources tab.
7. Uncheck “Use automatic settings” to manually change the resource settings.
8. In the “Settings based on” drop down menu, choose a configuration that will eliminate the error code. Usually, configuration 0004 or 0005 will work.
9. Choose OK and YES to further dialog windows.
10. Verify that there are no markings on Modems, Multifunction adapters or Port devices in Device Manager.
If this is not successful, the third possible solution is to contact your laptop manufacturer to Update the BIOS of the PC.
