Recently, I have switched to Windows 8. Most devices and apps I had on Windows7 works well in Windows8, but I am unable to connect my Micromax MMX353G USB dongle to Windows 8. I can install its modem software in Windows 8, but the device software will not detect the USB dongle and displays “No device” even though the USB dongle is plugged in. After a few research, I solved this issue. Here is how it is.
First, close the Micromax USB manger from desktop and exit the Micromax MMX353G USB dongle completely from system tray (right click and choose exit). Then, go to C – Program Files – MMX353G USB Manager – Driver.
Locate the file “InstallDriver.exe” and run it. After installing the driver, restart your computer and open “MMX 353G USB Manager” from desktop.
Open Device manager (just start typing device manger from Windows 8 start screen), and expand “Others”. Uninstall all “USB modems” listed that has a question (?) mark.
Now Search for hardware changes by right clicking device manger name.
After completing the hardware changes search, exit modem Software (MMX 353G USB Manager) as well as USB dongle from system tray.
Start the MMX 353G USB Manager. The software will detect the modem and now you are ready to connect.
