Easily, you can find some posts online telling that you can prepare a male-male USB cable, dismantle the device, shot the boot points, power on the device, connect usb to computer, release the shot pin, and then the computer will detect one COM port.
Waring: this shot-pin method may damage your PC motherboard because of power surge, and several cases have been witnessed.
In fact, for the firmware versions which are equal to or higher than 21.313.xx.xx.xx, Huawei has blocked the usb mode, and the device manager of Windows would give 'unknown device detected' message when connect to computer via USB male - male cable.
Conclusively, shot-pin method has the following disadvantages:
1) one male-male USB cable required;
2) dismantling the device will void your warranty;
3) more Windows driver issues;

2. locally upload universal firmware.
Only two steps will fully avoid the 4 disadvantages above and simplify the total process.
