This allows your devices act as a USB mass storage like external hard drive or thumb drive.

Kernel support
Currently, the g_mass_storage module is not compiled as part of default kernel configuration.
To enable this, follow same kernel building information as previous section USB Ethernet support but instead of compiling 'Ethernet Gadget', select the following to 'm':
Linux File Cd Gadget Usb Device Driver Version: 802JFAj. Linux File Cd Gadget Usb Device now has a special edition for these Windows versions: Windows 7, Windows 7 64 bit, Windows 7 32 bit, Windows 10, Windows 10 64 bit, Windows 10 32 bit, Windows 8, Windows Vista Enterprise (Microsoft Windows NT 6.0.6000.0) 64bit.
You can now continue following manual build howto to continue kernel compilation and installation.
Preparing shared storage device
See 'Backing Storage for the Mass Storage Gadget' for full instructions and recommendations.
Be aware that shared storage cannot be used in 'read write' mode if both systems (device and host) are using it at same time except if you accept to corrupt your data..
An existing physical partition or a logical volume can be used as shared storage device; another option is to use a flat file as shared storage.
Creating a sparse file
Use 'dd' command's 'count' and 'seek' options to create a 1GB file that will not use storage until it is used:
Partitioning and formatting sparse file
To be recognized by most Operating Systems, create a single FAT type partition and format it as DOS filesystem using Linux loop device driver.
![]() ![]() Create a single partitionFind partition offset
First partition starts at first sector: offset = 1 * 512 = 512 bytes
Set up loop deviceFormat deviceTest deviceRelease device
As we can see below, 1GB sparse file is only using 2.1MB storage (size of filesystem metadata):
Exporting mass storage / Loading the driver (on the device)
It looks like g_mass_storage conflicts with g_ether, remove g_ether first (if previously loaded):
Load g_mass_storage specifying storage to share (can also be a physical partition or a logical volume):
We can now plug device to another host and use it as USB connected storage.
Notes: Surprisingly it works well my Mac OS hosts (device automatically appears in Finder, I can copy and read files) but not with my Linux hosts (device appears and disappears constantly and cannot be mounted). Microsoft tts japanese japan download pc. Not tested with Windows hosts.
Emulating a USB CD-ROM
The g_mass_storage module can also present an optical drive to the USB host. For this, your backing storage should be a suitable filesystem image - usually an .ISO file. Pass a 'cdrom' module option like this:
(This can be useful with old PCs where the BIOS may have trouble starting from USB sticks, but supports booting via USB-CDROM.)
Note: As of Linux v4.7-rc2, the g_mass_storage driver can only emulate CD-ROM drives, not DVD-ROMs.

This document presents a Linux-USB 'Gadget'kernel modeAPI, for use within peripherals and other USB devicesthat embed Linux.It provides an overview of the API structure,and shows how that fits into a system development project.This is the first such API released on Linux to addressa number of important problems, including:

Most Linux developers will not be able to use this API, since theyhave USB 'host' hardware in a PC, workstation, or server.Linux users with embedded systems are more likely tohave USB peripheral hardware.To distinguish drivers running inside such hardware from themore familiar Linux 'USB device drivers',which are host side proxies for the real USB devices,a different term is used:the drivers inside the peripherals are 'USB gadget drivers'.In USB protocol interactions, the device driver is the master(or 'client driver')and the gadget driver is the slave (or 'function driver').

The gadget API resembles the host side Linux-USB API in that bothuse queues of request objects to package I/O buffers, and those requestsmay be submitted or canceled.They share common definitions for the standard USBChapter 9 messages, structures, and constants.Also, both APIs bind and unbind drivers to devices.The APIs differ in detail, since the host side's currentURB framework exposes a number of implementation detailsand assumptions that are inappropriate for a gadget API.While the model for control transfers and configurationmanagement is necessarily different (one side is a hardware-neutral master,the other is a hardware-aware slave), the endpoint I/0 API used hereshould also be usable for an overhead-reduced host side API.
