Problemi con Webcam Notebook/Troubles with Webcam Notebook
*---------------------------------------------------------[Italiano]-----------------------------------------------------------------*
Salve a tutti. Ho comprato una webcam notebook, ho installato i programmi necessari, ma quando vado ad aprirli, il led luminoso della cam si spegne e non posso visualizzare nessuna immagine. E' come se la webcam smettesse di funzionare. Qualcuno mi venga in aiuto vi prego! Come posso risolvere questo problema? La stessa cosa mi capita con MSN Messenger. Appena voglio regolare le impostazioni della cam, la luce si spegne. Ringrazio in anticipo tutti coloro che mi saranno d'aiuto.

Searching on the web, most results I found lead to this page, where it is said that the problem is due to badly tuned overcurrent protection, and advocated that unplugging and switching off the computer for a little while gets things back into normal. This does not really work for me; the problem seems to occur more randomly, unfortunately with high probability (my camera is available after less than one boot out of ten).
I tried to ensure that the ehci-hcd module is loaded at boot with the ignore-oc option (with a file in /etc/module-load.d/), to no avail.
I also wrote a script which alternatively removes and reloads the ehci-pci driver until my device is found in lsusb. It is sometimes helpful, but usually not. And even when my device is found that way, it can only be used for a while before disappearing again.
Anyway, such a hack is unacceptable... So, my questions are:
is it indeed related to overcurrent protection ?
is there anything else I can try ?
should I file somewhere an other of the numerous bug reports about "unable to enumerate USB device" already existing ?
If of any importance, I am running linux 3.15.7, because at the time I installed my system, I couldn't get the hybrid graphic card Intel/AMD working under 3.16.

Hi I am having trouble with my optia pro webcam. When it turns on it shadows with black and then progressively get's worse. I am using Windows Vista. Is there a link or download that will solve this problem. Thanks
Thanks for the replies, everyone.
I've made some progress. Like I said, before this problem occurred, I had to start my laptop's webcam software (CyberLink YouCam) before starting my .Net applications. If I failed to start YouCam, instead of a video feed I would receive an image from YouCam
instructing me to start YouCam. This is annoying because I have to run YouCam, which is not a light program, along with my stuff.
I wanted to find a way to run my .Net stuff on its own, so I began experimenting, which included uninstalling YouCam. After uninstalling, .Net couldn't get the video feed at all, so I reinstalled. This is when the weird error above appeared, but only for
SOME projects, oddly.
Last night I experimented further. I have three versions of Visual Studio on this system, so I pulled up 2010 to give it a try. Same issue. This lead me to believe the issue was not only outside of my code, but outside of project scope all together.
After a system restore to a point prior to uninstalling and reinstalling miserable YouCam, my video programs worked again, meaning I still have to start YouCam. It seems YouCam is monopolizing something, or maybe the un/reinstall messed something up.
The method I'm using from Emgu CV library is called Capture(), which creates an object to access the video feed. By default, it accesses the default camera. However, you can specify with an index a different camera. I'm suspicious that YouCam might be creating
a virtual webcam and making it the default, so perhaps if I specify a different index, I'll be able to access a camera directly.
Further thoughts are appreciated. Thanks. -
Hey, I am having trouble with my webcam. I can see the other person just fine, but he can NOT see me. When I went to tools and options it said that the webcam was working, but it is not comeing on (aka the light doesnt come on) and he can not see me. I havent had trouble with it untill now. How can i fix it?
If your contact has a video camera but you cannot establish a video chat then there may be a compatibility issue/limitation between the versions being used. Find out what version of Skype your contact is using. If it is an older Skype for Mac version, iOS version or similar and that contact is unable to upgrade to the latest release due to Hardware/OS limitations, then you may have to downgrade your client to a version that is video compatible with your contact's. I believe that may be at least a Skype for iPad release 4.6.306. Unfortunately older releases are not available from Skype as the iTunes Store only seems to carry the latest release.
Using your discretion you can however do a websearch for "Skype for iPad 4.6.306.ipa" or something similar and easily find versions that are available for download from 3rd party sites. If you kept a backup copy of that previous release then you could re-install it as well. With the .ipa file you can place it into your iTunes Apps directory and attempt to downgrade to that version when your iPad is connected.
This video compatibility issue is also mentioned here as well:

AUDIO PROBLEM WHILE USING OR ALONG WITH WEBCAM
Hi friends,
SUBJECT : AUDIO PROBLEM WHILE USING OR ALONG WITH WEBCAM
I'm not getting any sound while using web-cam.
I tried recording my voice , and played.. i can see my video but audio
Do we have any settings where i need to cross-check to make sure that everything being turned-on ?
My laptop details:-
HP Pavilion dv6 laptop
Operating system Installed - Windows 7
Can someone help me with this?
Thanks
kiranHi,
not sure if coincidence or the same question, but the same question got asked internally. The seeded option is required to get the OJSP filter installed. Here's the internal response
ADF View integration with MDS not configured
In web.xml, you need to have mds-ojsp intg enabled to load jspx base + customizations from MDS. In your web project in Jdev, go to ADFv project properties and select “Seeded customization” property. It would enable mds-jsp engine configuration in web.xml. If you want to use user personalization feature at runtime, you would need to select “User customization” property as well which would enable ADFv change persistence config in web.xml.
Warning: Some of the metadata under ... is packaged as part of both WAR and MAR. This metadata cannot be accessed from WAR using MDS.
For these two packages, you are including the files in both WAR & MAR. This warning conveys that since these base files are being put in MAR, at runtime they would be read from mds repository & not from WAR.

I HAVE PROBLEM THE WEBCAM IS NOT WORK

You can try to redownload isight or just buy a webcam. Justmake sure to buy one that is compatible with mac.
Completely irrelevant to the OP's issue.
There are no webcams that work with iPhones. The OP was referring to the camera on the iPhone.
Please try to keep comments relevant to the discussion. -
Hi, i am having trouble with my mac mail account, i cannot send or receive any emails because of the server connection problems. Message says it could not be connected to SMTP server. Thanks in advance for your help.
Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

Problem with Flash Lite in Nokia 5800 XpressMusic-Problema con Flash Lite en Nokia 5800 XpressMusic
I've got a problem playing videos in YouTube with my 5800. Recently I updated my version of Flash Lite to 3.1, from that day I can't see correctly videos on YouTube, when the the indicator of the bar reaches 1/4 of the totallity of the bar, the sound and image stop, but the indicator continues playing. If i want to see completly a video I have to put the indicator in the start of the bar and wait the load again. Some idea to fix this problem?
Sorry for my English level.
Tengo un problema reproduciendo vídeos en YouTube con mi 5800. Hace poco actualicé la versión del Flash Lite a la 3.1 y desde entonces no puedo ver correctamente vídeos de YouTube, cuando el indicador de la barra alcanza 1/4 de la distancia total, se detienen el sonido y la imagen, pero el indicador continúa como si siguiera reproduciendo, es decir para el vídeo es como si siguiera reproduciendo pero ni el sonido ni la imagen continúan., para ver los vídeos tengo que llevar el cursor de carga al principio y esperar la carga de nuevo, es un problema realmente molesto. ¿Alguna idea para solucionarlo?Hi,
I have Nokia 5800XM as well. The YouTube videos are playng fine for me. my FW is 40.0.005 with FL3.1
Maybe you need to update your device's firmware and FL version.\
Start Device Manager application on your 5800XM from menu or dialing *#0000#. It will check for new updates and ask you to download them. Remember that these updates are in MBs. I'd recommend update using a WiFi connection or flat-rate data plan.
Best,

I'm having trouble with back to my MAC. I had everything working on my home wifi network but now I am at my daughter's house and trying to connect via a verizon hotspot wifi connection. I'm wondering if the Verizon hookup is a problem.
I finally figured it out. Needed to update her Airport firmware and allow guest access, and also changed Sharing preferences to Allow Access for All Users.

I am having trouble with the cache in bridge. When i open I get a message saying bridge has encountered a problem reading the cache try purging in the central cache to correct the situation. I did that but now when I try to get to the folders where my photos are stored bridge never gets to where I can work. The message appears "building criteria" and I get an endless loop on the lower left panel. How do I correct?
You correct it by leaving Bridge alone until it finishes rebuilding its cache, overnight if necessary.

I am having trouble with the music from my bluetooth "skipping" on my IPhone 5. I thought that this was an antiquated problem with the new technology. It's very frustrating to purchase all of this music and expect great sound and playability and get "skipping". Any ideas on how to resolve this issue?
Does the issue occur when listening to the media using the speaker or wired headphones? If it does, the issue is with the media itself.
If it does not, it's likely a bad connection or interference. -
I have installed OS X Mavericks on macbook pro, macbook air & iMac but I am having terrible trouble with apple Mail. I need to take all accounts online frequently OR worse I have to quit mail and restart computer. Is anyone else having problems?
I just checked to see if the update to OS X Yosemite 10.10.1 solved any of the issues outlined in my previous post, and to my dismay, nothing has changed -- all of the previous problems persist.
My iMac (8) -- it's renamed itself eight times since the recent troubleshoot with the Apple tech rep -- shows up as a shared device in Finder on my MacBook Pro, but when I click on it, I cannot establish a connection using "Connect As". So I've attempted to connect using the menu "Go/Connect to Server...", using both (alternately) the iMac's name and IP address, to no avail. I get a message which reads: "There was a problem connecting to the server 'Peter's iMac (8)'. This server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
Here's what I know:
The server -- Peter's iMac (8) does exist;
The server -- Peter's iMac (8) is available at this time;
The server name -- Peter's iMac (8) -- is correct, as specified in the system sharing preferences;
The server IP address is correct, as specified in the system sharing preferences;
The network connection is active when I attempt to connect.
I'm convinced the problems stem directly from the OS X Yosemite update. None of this was ever remotely an issue in the previous OS X's -- any of them. This is maddening! What can be done? Apple?? Anyone??? -
I am having trouble with the initial connection of the apple tv. I have isolated the problem to the cable/connection. My new hdmi cable has a resolution up to 1080p...does the resolution matter?is this the right hdmi cable for the apple tv?
There are only two types of HDMI cables (standard and high speed - listen to all 1.2, 1.3 etc etc nonsense they will try to tell in the store) both types will work with the Apple TV.
The cable may be faulty though, have you got another to try, what exactly is happening. -
