Linux 3G modem with USB 3.0 support?

Question

linux

Hello Khabrovites.
I have a laptop that has all USB ports version 3.0. OS - Linux Mint 13. The current Huawei E1552 / E1800 modem can work in two modes:
1 mode) as a flash drive with drivers
2 mode) actually, the modem
The device starts up as a modem and is visible in Network Manager only if it was connected before loading the OS. If after, then it is defined in the system as a flash drive. All disembodied attempts and games with usb_modswitch did not lead to a successful transition to modem mode.
Therefore, I want to ask if there are modem models (it doesn’t matter which manufacturer):
1) having only a single mode - modem
or
2) even if it has two modes, you can start the second mode on the USB3.0 port without much dancing with a tambourine.
PS. And if it supports LTE, then generally chic.

Answer 1

Everything is simple.
Find the tty of your modem:
ls /dev/ttyUSB*
Then, using minicom, go to this tty and enter the desired modem mode:
AT^U2DIAG=0 (device in modem only mode)
AT^U2DIAG=1 (device in modem mode + CD- ROM)
AT^U2DIAG=6 (device in network card only mode)
AT^U2DIAG=268 for E1750 (device in modem +
CD-ROM + Card Reader mode)
AT^U2DIAG=276 for E1750 (device in network
card + CD mode) -ROM + Card Reader)
AT^U2DIAG=256 (device in modem mode + Card Reader),
you can use

Answer 2

I have a skylink modem that works the same way. But my crutch is simpler, I stick it in a flash drive, if I press "eject the flash drive" then it becomes a modem.
