thank you for your help .

You should check first on device dashboard if firmware version matches one that is shown in our guide, because no other version is supported for it.

yes i m sure it is the same version in guide
Huawei E5577-321 Zain with firmware 21.200.05.00.375

Then you should check basics that cause detection problems:
Make sure all drivers are installed or whatever else comes in device's drive
Make sure modems connection software/WEBUI/Dashboard is installed, but not running.
Make sure modem is not connected to internet.
