Carefully looked at the logs and figured out the problem itself, the modem was connected via the USB the extension with blue, so the modem was not visible, he told another extension agent white, the modem is visible through it! What do you think this is due to non-compatibility of USB punctures?

usb white blue

Maybe help the installation of additional plugins in the firmware? Any ideas?

So USB2.0 cable works but USB3.0 cable does not?

I am not sure if USB2.0 or 3.0 make difference. Maybe just cables too long.
