M.i.r. Srl USB Devices Driver



  1. ST and its partners have an assembled a comprehensive ecosystem to provide a wide range of software tools to support developers. These include tools for our STM32, STM8 and SPC5 MCU families, as well as tools for Audio ICs, digital power conversion, motor control and a number of simulators.
  2. This is the portable edition of FlashBoot, a powerful and simple-to-use program that enables users to easily create bootable USB flash drives, as well as install a mini operating system on them.
  3. Immediately after booting WInows 10, I can insert a USB flash drive and it's recognized and assigned a device letter. However, it I remove it and insert it later, device manager shows missing device driver (code 28). Attempts to update the drive fail with no driver found.

At the customer’s request, ecom’s mobile devices can ship from the factory with predefined custom configurations such as security settings, applications, and wireless setup. This allows devices to be used anywhere in the world immediately upon delivery — manual configuration is not necessary.

WIFI-2 is an USB 2.0 module compliant with IEEE802.11 b/g/n. It is based on a RaLink RT5370N chip and fully supported by the latest Kernel Linux versions.It can be mounted directly on a PCB instead of plugged in a USB port and works at 3.3 Volt. It can work in managed, ad-hoc and access point mode.

This module is available in two versions:

  • WIFI-2 which needs an external RF antenna plugged on the i-PEX MHF receptacle
  • WIFI-2-IA without the i-PEX MHF receptacle using the onboard PCB antenna

Both models are available with a 6 pin pitch 2mm solded on semi-holes to be plugged ona female connector or welded directly on the PCB.

Linux Kernel configuration

This are the driver to enable inside the Linux Kernel to support the WIFI-2 module:

  • Debian users will use the make ARCH=arm menuconfig command.
  • Buildroot users will use the make linux-menuconfig command.

Package installation

A closed firmware made by RaLink need to be installed. This firmware will be loaded on themodule at startup

Debian users
Buildroot users

In make menuconfig enable these flags:

We need also to install some utilities like iw and wpa_supplicant.

Debian users

Install iw and wpasupplicant using make menuconfig:

Buildroot users

Install iw and wpasupplicant using make menuconfig:

Network configuration to get access to a WPA-WPA2-protected Wi-Fi

Add inside the file /etc/network/interfaces the configuration for the wlan0 network adapter to add Wi-Fi Protected Access (WPA) or Wi-Fi Protected Access II (WPA2).

If, for example, my access point is called 'acme' and the password is 'ariettag25' write inside /etc/wpa_supplicant.conf:

M.i.r. Srl Usb Devices Driver Adapter

It is possible to hide the password using wpa_phassphrase

and use the ae6a6e81dc55b2c769a36ebe7405a222cf26876515b7bfa4c17ad9db95a39d57 in place of ariettag25.

Restart wlan0:

After a while if the dhcp are working well you will obtain your interface up.

hiFace Two

High performance digital link between computers, tablet or smartphones and digital-to-analog converters

The hiFace Two is a high value-for-money ratio Digital-to-Digital Converter to turn your computer into the main audio source for every hi-fi system provided with a digital input.

If your hi-fi system includes a digital-to-analog converter, or when your amplifier or CD player have a digital input to use their internal DAC with external sources, then you can use the hiFace Two to turn your computer into a high performance music source.

Just plug the hiFace Two into one of your computer’s USB ports and connect its output to the available digital input in your hi-fi system: you’ll be able to listen to music files with a very high sound quality, be they MP3, CD quality or high resolution files.

Extremely easy to use, it’s seen by your computer as an audio card. No need for driver with Mac and Linux computers, the driver for Windows is provided.

hiFace Two works great together with…

Your hi-fi system

The hiFace Two is a digital link, therefore you only need your computer and your hi-fi system’s digital input.

A PC or a Smartphone and a Portable DAC with Headphones Amplifier

This is the simplest setup, which can deliver stunning sound if both DAC/amp and headphones are good quality ones.
