So far unable to work in LEDE/OpenWRT 19.0.1; but working on ubuntu 18.04.3 LTS and Windows XP/7/8/10

@hnyman help me.

Open Host Controller Interface (OHCI) is an open standard.
Universal Host Controller Interface (UHCI) is a proprietary interface created by Intel for USB 1.x (full and low speeds).
The Enhanced Host Controller Interface (EHCI) is a high-speed controller standard applicable to USB 2.0. UHCI- and OHCI-based systems, as existed previously, entailed greater complexity and costs than necessary.
Extensible Host Controller Interface (xHCI) is the newest host controller standard that improves speed, power efficiency and virtualization over its predecessors.
Virtual Host Controller Interface (VHCI) refers to a virtual controller that may export virtual USB devices not backed by physical devices. For instance, on Linux, VHCI controllers are used to expose USB devices from other machines, attached using the USB/IP protocol.

Installed
kmod-usb-ehci kmod-usb-ohci kmod-usb2
but still not working

12

should be like

Port 1: Dev 8, If 0, Class=Mass Storage, Driver=usb-storage, 480M

but unable to so ...

14

From what I remember, I only had to install 3G protocol and the USB drivers and my 3G USB was successfully identified and started working. I did this in v15.05.x so I'm not sure why this is not working for you.

15

Will you convert the below usb_modeswitch.d to equivalent usbmode-json

Once again removing the file /etc/usb_modeswitch.d/1c9e\:f000 resulted in unable to detect as modem, and out put as shown below on Ubuntu
