Qualcomm HSUSB device driver issue I have a Qualcomm HS-USB device on which I want to test my developed application. The problem I am facing is that the device drivers are not getting installed. I have tried the following steps:


Downloaded the Google USB drivers (latest).  
Downloaded the ZTE USB drivers (the device is ZTE manufactered).  
This device I have configured earlier also on a Windows 7 system and it worked fine. I dont know why it is not working this time on a new Windows 7 system. 


Please help me to make the device driver work. Or please tell me if there is any other solution to this.
As for all driver problems, you should first try the following:


Disconnect the device
Uninstall all drivers for it
Reboot
Install the official drivers (probably the ZTE-specific ones)
Reboot
Connect the device
