In my C++ Windows application, my users can plug in their mobile device via USB and my application can transfer specific files to/from the device. For Android devices, I was able to use MTP. But iOS devices have me tripped up (I'm not an iOS user).
Immediately, I saw that MTP wasn't an option as I couldn't view the device's filesystem via Windows Explorer (wasn't expecting that). So now I'm stuck, and confused. Googled like crazy and all I discovered was that other 3rd party programs can do it, but I can't find any documentation or resources as to HOW.
Can someone point me in the right direction? What would I need to do in order to view the filesystem on a connected iOS device? Are there any libraries I may be unaware of that I can't find? I can see that iTunes has the functionality I'm looking for.
Thanks for your time!
Well, it looks like my comment was wrong. There is at least libimobiledevice http://www.libimobiledevice.org/ and https://github.com/libimobiledevice/ifuse that claims to still support access to the iOS device file system and even claims to be cross-platform. I haven't tried it though to verify if those claims are true.

OK, first I shall point that I am completely new to Windows Apps Development, which is good, since I am trying to develop a Windows Store App for PC to use a PrimeSense Scanner connected via USB. I have asked a more specific question about this here.
This time I have a more generic question, which is more related to Windows Store app development. I am using VS2013 Express and compiling for Win32.
When I compile my application for VS2012 and run it as an execcutable file, I can connect to the scanner perfectly. But I can't do the same with VS2013 and running it as a Store app.
I know the device is connected and the drivers are updated and all dlls file placed in the Widnows System 32 directory.
I have also added all Capabilities to the App Manifest and also added the following Device Capability
<m2:DeviceCapability Name="usb">
<!--OSRFX2 Device-->
<m2:Device Id="vidpid:1d27 0609">
<m2:Function Type="classId:ff * *" />
<m2:Function Type="name:vendorSpecific" />
</m2:Device>
</m2:DeviceCapability>
The vid and pid, obviously match the corresponding codes of the device.
One of the errors I recieve when trying to conenct to the scanner using OpenNI is:
Could not open to "\\?\usb#vid_1d27&pid_0609&mi_00#7&1601586a&0&0000#{c3b5f022-5a42-1980-1909-ea72095601b1}" USB Device not found
This error is quite frustrating since I know the device is connected. So I tend to think that there is some level os specificity on the Windows Store App side of the game that is not enabling my to connect to the device. As I said, I am compiling for Win32.
Is there a chance that the drivers will not work for a Windows Store App. Is there some extra stuff I should do inside the Windows Store App logic that I am not doing and that is necessary to connect the USB device? I am sorry, but I am completely new to Windows Store App development.
Thank you.
You can't do that from metro apps.
You typically create a handle to that usb device by calling CreateFile with that object mananger path as the file to 'create'. CreateFile is not allowed in metro apps - "desktop apps only" - and its 'replacement', CreateFile2, specifically doesn't allow opening object manager objects.
Furthermore, the documentation for CreateFile2 states that in metro apps this function can only open files and directories (and not things like pipes, mailslots, consoles, etc.).

Unless I missed something, I don't think this is possible.
I would like, from a native Windows application using C++, to receive video/audio data sent from a browser located in a remote location. It seems like WebRTC is the way to go for this.
Most information I find is about how to interact with the browser to write WebRTC apps, but it may case the data would be received by my C++ app. Is it correct that I would need to use the WebRTC Native Code package for this, which is described as being 'for browser developers'? Document is located here: http://www.webrtc.org/webrtc-native-code-package
And what if I want to send video/audio data that I generate (ie not directly coming from a webcam and microphone), would I be able to send it to the remote location browser?
Any sample code out there which does something like I'm trying to accomplish?
The wording in that link is a bit misleading. They intend people that are developing browsers to use the native code, and advise those that are developing "applications" in a browser to use the WebRTC API.
I have worked with their native code for over a year to develop an Android application that is capable of performing audio and / or video calls between other Android devices and to browsers. So, I a pretty sure that it is completely possible to to take their native code and create a Windows application (especially since they have example code that does that for Linux and Mac -- look at peerconnection client and peerconnection server for this). You might have to write and re-write code to get it to work on Windows.
As for as data that you generate. In the Android project that I worked with, we didn't rely on the Android device / system to provide us with video, we captured and sent that out our selves using the "LibJingle" / WebRTC libraries. So, I know that that is possible, as long as you provide the libraries with video data in the correct format. I would imagine that one would be able to do the same with audio, but we never fiddled with that, so I cannot say for sure.
And as for example code, I can only suggest Luke Weber's gitbug repositories. Although it is for Android, it might be of some help to look at how he interfaces with the two libraries. Probably the better code to look at is the peerconnection client stuff that comes in the "LibJingle" second of the native code. [edit]: That is located in /talk/examples/peerconection/client/ .
If you get lost from my use of "LibJingle", that will show you when I started working with all of this code. Sometime around July of 2013 they migrated "LibJingle" into the WebRTC "talk" folder. From everything that I have seen, they are the same thing, just with the location and named changed.
I'm looking to write an application that will allow me to control music, etc with a remote control. The infrared receiver I have is built into my MacBook Pro which is running Windows.
What I want to know is how can I go about this? Most of the information I can find online is specific to writing Windows device drivers and I'm having trouble finding out how to use drivers that already exist for a device.
Is it absolutely necessary for me to write my own drivers or is there a way to use the drivers provided by Apple?
On Windows you communicate with a driver by first opening it using CreateFile and subsequently sending commands to it using DeviceIoControl. You need documentation for the driver's API though to understand what functionality is available through which control codes and what parameters they expect. Digging up that information is probably the hard part.
I'm developing a PC c++ application running on windows. The application shall communicate with an android phone connected thru USB, using MTP. The idée is to not mount the Storage Card. What I have found is that Windows have something they call WPD (Windows Portable Device ) which supports MTP. It looks pretty ok but it demands WMP11 to be installed. What I wondering:
Is there are any other alternatives libraries you can use?
Do any one have any tips or experience about using WPD?
Are there any "leaner" dependencies you can install instead of WMP11 for xp?
Any help would be greatly appreciated.
I here provide some answers to my question for the hope that it will help some one else.
Is there any alternatives/leaner libraries?
You can use WIA but that is only used for images. but a part from that I have not found any.
Any tips?
Check out the sample code provided by Microsoft, it is a good start point. I found it be searching for Portable Devices COM API Sample on MSDN
For Services you can check out this sample code. Which I found by googling for WpdServicesApiSample
The WPD api is pretty ok to use.
Not all devices support MTP and some only support part of it. This caused me some problem but the device we used released an update which supported more of MTP
I found the answer about XP-problems from this StackOverflow by pcbbc really helpful. I can also add that we mailed the supplier and asked for a custom .INF file to support XP and they were really helpful and provided us with it. But it took some time before we got it.
I wish to make an SMS analysis tool that downloads the SMS.db file from an iPhone device, connected via USB. I am coding in C++ and would like to know how applications such as DiskAid and iPhone Explorer access the entire filesystem via USB?
Thanks in advance!
iPhone Explorer requires iTunes; probably it works by employing the iTunes COM API (I know there is one). Anyway, it does not show the full filesystem; just the parts that iTunes exposes. And AFAIK, the SMB.db is not exposed.
Or maybe it taps into some lower-level API that iTunes itself consumes.
Not sure about DiskAid.
I imagine it will use either Manzana, or something similar to it. It uses one of the iTunes libraries.
