On some systems it appears that there is a communication issue between the K3760 (USB Stick Pro) and the Vodafone Mobile Connect Software resulting in the error 635 when attempting a connection. The following steps have been detailed to resolve this error.

Steps:

1. Confirm Modem Interface is present in Manage Devices:

• In the Vodafone Mobile Connect (VMC) Software go to Manage Devices. If the “Globetrotter GI41x - Modem Interface” is present proceed to step 2
• If the “Globetrotter GI41x - Modem Interface” is not visible under Manage Devices, leave VMC open and go to Windows Device Manager
• Expand the Universal Serial Bus Controller heading, right click on the GI41x and select uninstall
• Once the component has been removed from Device Manager go back to VMC Software and Manage Devices
• Highlight any/all “Globetrotter GI41x” components and select remove
• Shut down VMC using File and Exit
• Return to Windows Device Manager and go to Action and select Scan for Hardware Changes to reload the device components
• Relaunch VMC and go to Manage Devices
• Confirm the GI41x Modem interface is now present

2. Set the Modem as the Default Interface

• In the VMC Software go to Manage Devices and ensure the “Globetrotter GI41x - Modem Interface” is ticked as Default
• Click Apply and OK to return to the main screen

3. Retest Connection

If issue reoccurs due to device being plugged into different USB port do the following:

• Shut down VMC using File and Exit
• Go to Control Panel, Phone and Modem Options and select the Modem tab
• Check for multiple references to the “Globetrotter GI41x – Modem Interface”
• If more than one reference then highlight each entry and select Remove
• Once all entries to the device have been cleared click Add, Next and Finish to reset the entry under Phone and Modem Options
• Relaunch VMC and retest
• Repeat steps for any additional USB port as required
