Most Huawei modems come with "Plug and Play" drivers stored on the device itself.
Open the drive and run AutoRun.exe or Setup.exe to begin the background installation.
Connect the E5372s to your PC using a high-quality micro-USB cable.
Wait for the installation to finish. Once done, your modem should appear in Device Manager under "Network Adapters" or "Ports (COM & LPT)". 2. Huawei Official Support Tools
