UMS Interface

This program allows you to chose a block device or disk image as a 'disk',and communicate with PC through usb mass storage (just as usb disk do).Root permission is needed.

introduction

quick start

usb connection: set current data source as U disk
mount to: mount current data source
quick create: create a image with the given size,format as vfat,mount it,and use it as U disk

*If the file you just copied can not be displayed immediately, try click 'close'/'launch' and 'umount'/'mount' continuously.

U disk

block device: Representing a disk or partition, usually located in /dev/block or /dev.
image file: Usually named as *.img .An image file with a file system can be mounted like normal disk.
data source: source of the data in U disk,an image file or a block device is available .
config path: path this software relied.Like /sys/class/android_usb/android0 or /sys/devices/virtual/android_usb/android0.
readonly:may have no effect for some phone

mount

data source: source of the data to mount,an image file or a block device is available .
mount point: chose a directory to mount.
file system: will be automatically chose if not specified.
mask: used to set dmask and fmask.

*You must disable 'mount namespace separation' in SuperSu, or it won't work.

create image

format: create file system for image file.

It can be used as a boot disk for PC when select a solved image.

简介

快捷启动

U盘连接: 将当前数据源作为U盘,点击'终止'取消
挂载到: 自动挂载当前数据源,点击'终止'取消
一键启动: 点击创建,创建指定大小镜像文件,格式化vfat,并将其挂载,同时作为U盘使用

*如果刚复制的文件无法立即显示,尝试连续点击'关闭'/'启动','卸载'/'挂载'.

U盘

块设备: 代表一个存储器或分区,通常位于/dev/block 或 /dev.
镜像文件: 通常命名为*.img .一个内含文件系统的镜像文件可被挂载,和普通存储器一样使用.
数据源: 可选任意镜像文件或块设备.若选则块设备,请谨慎操作,以免数据丢失.
配置目录: 通常会自动寻找,可点击"选择"以手动指定.多数手机上此目录为 /sys/class/android_usb/android0 或 /sys/devices/virtual/android_usb/android0.
只读: U盘只读,很多手机上可能无效

*由于内核原因,使用三星芯片的一些手机使用此功能会被作为CD ROM

挂载

数据源: 可以指定内含文件系统的镜像文件或块设备.
挂载点: 指定一个目录,"磁盘"中的文件会被放到这里.
文件系统: 忽略,会自动判断.
权限掩码: 用于挂载vfat时指定文件访问权限.

*SuperSU 中的"挂载空间分离"可能会影响本功能,可尝试在SuperSu中取消.

创建镜像

格式化: 为文件建立文件系统,以便立即挂载.
可将启动盘的磁盘镜像作为U盘的数据源,这样便可方便的将手机作为电脑启动盘.
