I have a usb driver with multiple IOKitPersonalities each with a IOMediaIcon entry. all works fine if the usb devices are plugged in after the kext has been loaded (kext loads fine, is signed, etc.). but after reboot of the computer, only ONE of the usb devices shows the standard orange default usb image. if I unplug/reload kext/replug the usb device in, the image gets corrected.
Any thoughts?
(Details:
running Mac OS X 10.10.1 (I don't think I saw this problem before Yosemite, definitely not a problem on 10.6.8), all the Personalities are the same (except for the IDs (which are correct I think since the usb device loads correctly if I plug in after the kext is loaded) so it isn't mistake with the personality...)
I don't know how to fix your specific problem, but I can give you some pointers which may or may not be helpful (sorry, a bit too big for a comment, but not a proper answer):
The icon stuff is handled in user space, the only thing that the kernel should have to do in theory is set the IOMediaIcon before registering the service. Setting it in the personality should be fine.
In user space, Disk Arbitration takes over. You can download (most of?) the source code for it from Apple's Open Source Site.
A quick search reveals that the diskarbitrationd source code does indeed reference the IOMediaIcon, in DADisk.c
I don't know how well it works to recompile diskarbitrationd and substitute Apple's binary with your own, but if that works, maybe you can modify it to log output from the icon code, and get closer to your answer that way?
The other source of error I can possibly think of is that although the system gets the correct icon information, it can't actually find the icon file? I've heard about various bugs related to bundles and resources in the context of /System/Library/Extensions vs /Library/Extensions since they added the latter. If your icons are in your kext bundle, and you've switched to /Library/Extensions, try switching back to SLE.
I hope that helps your debugging efforts!

I have installed Domino Designer in a Windows VM on VirtualBox on OS X.
When I start entering code in the JavaScript editor, Domino starts to work for every letter I type. The hourglass icon appears and the network symbol on the status bar flashes. This operation takes up to several seconds for every letter I type.
If I try to type anything before the hourglass disappears, the keyboard may hang up and the result is a long list of the same letters that I have to delete again (causing the hourglass to appear for each letter I delete again).
I have tried to disable functionality like "Content Assist", "Quick Diff" and other helpful stuff without luck.
I would really appreciate hints or tips to make this nightmare vanish...
I've not used domino designer, but first thought would be that your VM isn't handling the processing required by the designer.
What are the specs on you windows VM? Did you allocate enough RAM, for example? Make sure they match the requirements to run the designer:

Thanks to Joel for leading me into the right path.
I did several things, and together it now seems that I have a much better environment. I still see the hour glass from time to time, but it does not mess up my code anymore, and most of the time it does not bother me.
What I did was the following:
Changed the memory settings for Domino in this file:
[notes dir]\framework\rcp\deploy\jvm.properties
New values:
vmarg.Xmx=-Xmx1024m
vmarg.Xms=-Xms512m
vmarg.Xmca=-Xmca512k
Then I changed the virtual memory of my guest Windows install to a fixed swap file of 4096 MB.
At least I connected my Mac to a faster network using Thunderbolt to Ethernet cable adapter. I don't think the last thing did any difference, but at least I now have a faster and more reliable network connection.
I tried rooting my S2 but something obviously went wrong. When i was finished rooting and tried rebooting it, it was just stuck on the bootscreen with the yellow triangle. I went to sleep and the next day it was still like that, so I went on the internet to find some help. I found the stock rom and kernel and tried booting that. Now what happens is that the boot screen comes and after 10 seconds the phone just turns off. When i tried unrooting it, i couldnt because Odin wont recognice my phone. I have also tried using Heimdall, but that wont find my phone either.
I have the international version, think it's called something like I900 etc.
I tried asking on Reddit and when they couldnt help me, they sent me here. I also discovered that i forgot to put the phone in debugging mode.
I can still acces the download and recovery mode, and yesterday i ordered a USB jig, that will be coming in the mail soon.
What should i do?
It seems you flash a wrong kernel/Image. Try to get a Orginal Kernel and a Orginal Rom.
Together with the correct PIT File.
Be sure to check if you have a 9100 or a 9100G .. this is different processor.
If you get into the Download Mode... all can be fixed.
If you get an Screen with 3 Symbols (Phone, Triangle, PC)
You are in the First Stage Bootloader, and must repartition Flash.
Odin should always detect your Phone.
Please search for Recovery Flash, or unbrick in some Android-Forums...
I don't want to link because there were many good sites.
Hope this helps.
PS: Flashing isn't automatically Illegal.
I'm Software-Developer and need sometimes to root Smart-phones, with custom kernels for different Projects.
For rooting There are 2 apps which will help you to have superuser permission on your device-one is superuser and the other one is
I recommend supersu over superuser.
Supersu also has an option to install via clockworkmod recovery(can be installed via rom manager) So it becomes an system app.
I would like to change the output mode of an Intel GMA450 based graphics chip to "cloned" mode.
Since the environment is a Windows Embedded Standard and only one of the connected monitors might be visible for the enduser, I would like to either permanently set the output mode to cloned or reset it continuously to cloned mode in case the actual mode differs (e.g. after a reboot, disconect/reconect of the second monitor or by other means).
Is there a way (Registrykey, API for the Intel driver, Win-Api) to change the display mode to cloned / dual output programatically?
Update:
I found the SDK for the IEDG driver it seems that I might be able to programatically set the resolution, clone mode etc.
However, I can't find the SDK or any information for the driver I am currently using: Intel® Graphics Media Accelerator Driver for Windows* XP, version 14.32.4.4926.
This isn't a good answer, but it might get you headed in a direction to figure it out.
My last laptop had an external monitor connected, and the Intel drivers would often be confused about the orientation of the secondary after a reconnect or a reboot. I got tired of dealing with that and tried to fix it programatically because the clicks were too many in the GUI. Select this monitor, select rotation, select other monitor, select rotation, apply, arrange, apply, wait...
I spent about a day on it (ahh, the days of being an employee vs. self-employed!) and the solution I found was to use a program to compare the registry (regshot perhaps?) to discover what keys were involved in the correction (what they were before versus what they were after) and then there was an intel-provided exe that forced the driver to reset based on the registry-- the exe was essentially like pressing the "apply" button in the gui. I was running XP and if I recall, the gui management was for configuration of the Intel Graphics Media Accelerator Driver for Windows XP as well. So the final solution became a cmd file on my desktop that would apply a REG without confirmation and then run an exe with some parameters.
Now, I don't have that laptop (they didn't let me walk out the door with it when I quit!) and I do not remember the specifics on the exe that was required to do the reset. Just changing registry keys didn't spontaneously cause it to take effect-- there was an api call involved, which I just handled with their exe. I know that isn't a lot to go on, but something tells me the file was in the driver package, or somewhere on the drive already, and I just found it. Running it at the command line gave options. Like /reset.
I hope that helps you a little. Be sure to post back if you figure it out.
Also post back if I'm completely mistaken and it didn't happen like this at all. But that's the way I remember it. :)
I have to make an application that will do the following:
Open a video file embedded in the application
Open some pdf files, preferably embedded in the application, but if it will have to open externally, it's no problem.
Work in fullscreen on the user computer, with a minimum resolution of 1024x768. I'm thinking about a resolution of 1024x768, centered on a black background.
I was thinking of using Flash, but I don't have much experience, so if there is another easier IDE that creates a Flash application, I would prefer that.
So, if anyone knows any Flash component to do this, I'll be very thankful.
Creating a Flash CDROM takes a little bit of care, but from my experience it's well worth it. From your requirements, the Flash IDE is well up to the task. The common requirements are as follows:
Windows / Mac platform
Flash Projector file
Autorun file (For the Windows platform)
Net access or all local
If your client is happy with creating the CDROM just for Windows, there will be very few dramas - but if they want to create a Mac-friendly version, you can do that too and I will explain afterwards.
Your Flash should preferably be an .exe projector file - the reason for this is so that the Windows user can open your app without downloading a Flash player (If the client wants a CDROM, they probably have limited net access, so this is a good thing!)
Within Flash, you can perform all your standard fs commands including full-screen.
You will likely need an Autorun file so that the user sees your application as soon as you put in the CDROM - simply create a file named 'autorun.inf' in notepad and enter the following:
[autorun]
open=yourProjector.exe
Where 'yourProjector.exe' is the name and path of your projector file.
It sounds like you're going to embed your videos and content in the CDROM - this is usually the ideal case, since your client won't receive annoying security messages, but this can also be a bad thing if you want to correct your content later (spotting errors after a thousand CDROMS have been distributed can be a PAIN).
You can serve some of your content online to avoid this, but it would give your user some ugly messages, so as long as you triple-check your content and embed everything, it would be the best scenario.
Now for a Mac, Apple has done away with autorun features years ago - there is a way to turn it on through Quicktime, but this is off by default for almost all Mac users, and turning it on is not recommended because it makes the Mac vulnerable to the 'Hong Kong Virus', one of the few Mac viruses around.
You can make your CDROM mac-friendly by creating a Mac Projector and adding instructions for how to use it by changing the background image of the CDROM window. I haven't had to do it before, but I hear that it's not too difficult.
You can use the Flash Projector. Here is a tutorial to get you started. Now, you won't be able to embed the PDF files but you can open them easily enough using fscommand("exec","foo.pdf")
You can create an Adobe AIR Application; however it won't run off the CD ROM; it'll need to be installed locally.
If creating a projector from Flash Pro doesn't work; look at a tool like Janus or Zinc
Right now I have Phonon working on windows with a DS backend. However, it will not play certain mp3 files and although it appears to be playing m4a files (the song progress bar keeps moving) no sound comes out. The application is built using PyQt4 on Windows and is aimed at Windows users.
I know that this is not the fault of my program as when I replaced a file with one that did not play normally with one that did, the song played perfectly. I have downloaded phonon vlc, and tried to build it, but I cannot get CMake to create a makefile. Whenever I try, it tells me that the dev-cpp gcc is not able to make a simple test file.
I also tried downloading clementine and amorak to see if I could get that to work, but I have had the same problems there as well. Has anyone run into this sort of problem before?
I've run into the same problem recently. It seems to be that Phonon has a bit of a hissy fit about ID3 tags, particularly compressed ones. I've taken to creating a temporary copy of every mp3 that I open and using mutagen to delete the tags from that copy. I then open the de-tagged temporary file using PyQt/Phonon, and everything works as I expect. BTW, mutagen is awesome.
Phonon does have a bit of a habit of failing reasonably silently. This is what I do: check if your MediaObject is in a Phonon.ErrorState; if so check its errorString(), usually some incomprehensible message. Google this message and try to work from there.
Edit: Hmm, interesting. It's not Phonon having the problem, it's the DirectShow backend not being able to play the file with the compressed ID3 headers. While the "fix" I outline above does work, I found I was still having problems playing other types of files, e.g. .m4a, despite having the right codecs installed.
The solution was to install the K-Lite Codec Pack, and use the Win7DSFilterTweaker tool that comes with it to change the default decoder for the various codec types from "Microsoft" to "ffdshow". You might also need to run the ffdshow audio decoder configuration tool and tick the box marked Show dialog when an unknown application tries to load ffshow in the DirectShow control tab.
