Why the modem disconnects by itself?

Hi. Maybe I have the wrong website, but I hope for your help.
In short, I have a 4G modem connected to the laptop via a USB extension cable, and is likely due to the lack of power. So the idea was born. If you disable the one not used me USB port on the laptop then addressed whether the problem or if the USB port is not involved, and food and so he doesn't need?

Solution
If the modem without extension is not disabled, then the laptop gives enough power to the port and issue in a passive extension cable.
If the modem without extension is also disabled - can help disable the other devices, and may not help.
Off only with an extension cord. What is the problem with passive lengthening, I don't know what it is? - savanah_Reichert commented on July 8th 19 at 16:11
The cheaper and thinner the cable the higher the resistance and more losses in the cable.
How long is you cable? - Daphne_Roob commented on July 8th 19 at 16:14
: there were three, was reduced to 1.8. The cable is quite thick. - savanah_Reichert commented on July 8th 19 at 16:17
: We really try to disable all unnecessary users, or to stick to the hub which has a separate power supply. - Daphne_Roob commented on July 8th 19 at 16:20
