Windows 7: Huawei USB Modem driver installation failed on Win 7 x64

04 Jun 2010   #11

Windows 7 x64

I have found the conflict. It seems that if we install any backup software (Norton Ghost / Acronis True Image), the driver conflicts starts. But I am yet to find the root cause of the conflict. I am suspecting COM Surrogate (dllhost.exe) as both the USB modem driver and backup programs use the same process dlls.

COM Surrogate (dllhost.exe) is an application that is often used by Windows Explorer to isolate itself from buggy codecs (if explorer would load the codecs in its own process, it would crash as it did in XP, so explorer spawns dllhost to actually process the thumbnails, etc. outside of its process space).

Windows 7 x64

Hi Guys, I have found a workaround.

Install the driver on Windows 7 after a fresh installation of Windows (prior to installing any system software or other devices drivers).

You may still find that Windows 7 do not find the driver when you plugin the usb device. The Plug-n-Play will not work. So the trick is to reboot the machine. At the time of booting connect the device and check if Windows detect the device.

Good luck.
