Inno setup installer trouble shooting (copying drivers from Hauwei Mobile connect setup)

Summary: I have copied the driver files from the official Huawei installer, to use in my own installer. However there is a problem. The drivers are installed OK during installation, but at the end of the install – the modem is not detected by Windows automatically (which is correctly done when using the offical Huawei install program). I need someone to analyse what is occurring in the official Huawei windows 8 installer, to see what refreshes the modem so it is detected during install. Then apply this to my custom Inno setup project. See "Inno setup installer trouble [login to view URL]" for full details Feel free to ask if you have questions. If you bid, please let me know how you will approach the problem - to help me choose someone that knows what they are doing. Thanks.
