USB device (Logitech QuickCam Messenger) stopped working (SOLVED)

Hey there,
I have a logitech quickcam messenger, which used to work perfectly 2 days ago. I updated my system yesterday and this morning, but I tried the cam again only now, and neither cheese nor webcamstudio work anymore (it never worked in skype since I moved from Mint to Arch a few weeks ago, but that was easily (and better) addressed by starting cheese and then using desktop sharing in Skype)
The webcam is recognized

SOLVED : really stupid problem, but well... I'll completement my post and leave it for anybody who might hit the same problem :
dmesg looked like this when after I started cheese :

[ 3816.917377] gspca: bandwidth not wide enough - trying again
[ 3816.938010] gspca: no transfer endpoint found
The (not so obvious) solution was to connect the webcam directly to the computer and not through a USB hub. I have no idea why it used to work and suddenly stopped, but it works again now.
sorry to take up your time, in case I did.

Since last update, sound on my Logitech Quickcam fusion stopped working?

In iChat ,I noticed that since the last apple software update the sound on my Quickcam Fusion stopped working only the video works.. I noticed that under preferences, video, then microphone, it is no longer listed as a USB device option. Only line-in is present.
I suspect it has something to do with the last software update from Apple. I think the details had mentioned that they changed something with USB security??
I would like this camera to work since I just bought it and it was working 2 weeks ago!
Thanks for any help.
Mini Mac OS X (10.4.10) latest version of iChat AV

New Audio Update toady for me.
Although this was on my MacBook Pro that I have just reinstalled the OS on.
(I can not find it in downloads. Strangely it has appeared after the 10.4.10 combo Update)
It may also pay to start up GarageBand odd as it sounds.
Also go to Applications/Utilities and open the MIDI Utility and make sure the setting is set to 44100

I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
Help.

BB1B2,
The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
Sorry,
Clinton

Logitech Quickcam Messenger no dice

So I have this logitech quickcam messenger, and suprise, its not working.
Anyway, i plug it in (USB), and several modules load, /dev/video0 is created, but other than that, no functionality.
Mostly when i try to run any video app I get (running motion):
[1] Failed to open video device /dev/video0: Device or resource busy
I can run cat /dev/video0 and get a lot of output streaming out, so thats a good sign. But I wonder is the device really busy or is the driver screwed up?
I'm using the quickcam_messenger module that autoloads when i plug it in.
I've also tried qcmessenger and gspca_zc3xx modules to no avail.

Old topic, but case is up to date.
I was struggling with my own older Logitech camera Quickcam Pro. Apparently I bought the wrong one, but finally I set it up with limited functionality.
Of course the problem was the driver. No pwc, no linux-uvc and not even spca5xx. I had to compile new driver module with nw802. Actually mine was nw801, but I just had to edit one file before compilation, apply some patches, insert this module and now it works.
Please do some researches and specify correct driver for your webcam using ProductID. Logitech webcams have varied set of drivers. :-)

After update to 11.2.202.228 mz USB 1.1 web cam stop working

Hi,
I have a camera from MediaTech company, it is written on it MT400 and serial number 2604050599. Before latest update it works, after install newest version of Flash Player it stop working. I tested it on http://testmycam.com as one of Adobe employee advices on forum but I have only black rectangle. On top left corner of this rectangle it is written Camera: USB PC Camera (SN9C 102) , FPS 10. I disabled Hardware acceleration but problem remains.
As I remember this camera is USB 1.1. Does new Flash Version support USB 1.1?
I have checked on Device Manager on my Windows XP Home Edition 2002 Version with SP3 device driver version it is written:
Manufacturer : Sonix
Driver date: 2004-04-02 (I can't find newer drivers on web )
Driver version: 4.6.6.1
Is it bug or Flash Player stops supporting such devices?
Regards

I pressed Allow, before pressing Allow background was grey, after Allow
it gets black. I see the name of this camera on list. I also try another
camera from Logitech (I can't remember what name was it, but one of the
newest) and everything works which suggest it is strictly related with
this specific camera which I'm using.
Regards

Mac Mini and USB 2.0 hubs (hubs stop working within a month)

I have an aluminum Mini running OSX 10.6.6 (Snow Leopard). With only 4 USB ports, I have need of a USB hub to accommodate my external drives and other peripherals: keyboard/mouse, camera and iPhone have to use the existing ports in the Mini (difficult access to ports due to space limitations), leaving one port for up to 4 external drives (older drives 40-60gb used for backup and extra storage).
I have problems using powered USB 2.0 hubs with this computer; I have 'burned out' 2 hubs since buying the Mini in February. They just flat out stop working, though they still show power (the power indicator light on the hubs); no peripheral is recognized when plugged into the hub (which worked fine for about a month). I can unplug the 'must use Mini ports' (camera, iPhone, charger, etc) and the peripheral drives are recognized and work normally when plugged directly into the Mini ports.
One hub was a Belkin 4-port hub (about 1 year old) and the other was a GE 3-port hub with several flash card readers (19-in-1 card reader), also about a year old. Is there any reasonable explanation why powered hubs would suddenly stop working, related to use with the Mac Mini 2010 aluminum version?
I had worse problems with the USB ports in an old (~2006) Mac Mini (out of warranty), where the USB ports in the Mini stopped working, which is partly why I bought the new mini. In light of this tidbit, (be honest, please) are there known issues with Mac Minis and USB?

Each of the external drives has its own power supply; I generally only use one drive at any one time, but on rare occasions I have powered up more than one to confirm or transfer files. I don't leave any of those drives on when not in use, and when everything is working I properly eject/unmount them before turning them off.
There have been times when I powered up a drive connected to a powered hub and both the hub and the drive indicated activity but the drive didn't mount. On those occasions the drives sometimes would not appear in Disk Utility, and other times would appear, but would not be "mountable". I didn't know what the best way to deal with that was, so I would just turn the drive off, hoping the lack of mounting on the desktop meant no real drive activity was occurring and I wouldn't risk data loss or drive damage. So far all the drives seem to work fine when plugged directly into the back of the mini.
The main external hard drive I was using when the Belkin hub failed (iomega 40g) is USB 2.0 only (no firewire). I have another drive that is only firewire (la cie 60g)... so it wasn't a factor. Two other external drives are ACOM, one 40g one 120g, and then there's my old iMac G5 disk (display fizzled and everything but the disk recycled through Apple's recycling program) which is mounted in an external enclosure and is part of the USB contingent, but is not being used for anything but backup (all three both USB 2 and FW400 capable). (I know, too many toys... but why throw them out?)
The USB hubs both had their own power supplies, too, and I never used them without power (though I tried it as part of troubleshooting, before reading the Apple article on USB and power requirements). Other USB devices that only work when plugged into the mac directly are my Epson Stylus CX4800 all-in-one, and my Radio Shark.
So, whaddya think? Should I risk buying another powered USB hub or just live with plugging in peripherals to one available USB port (through a short USB 2.0 extension) and only use one at a time? That would be a bit of a pain, but if there are no issues you've heard of with Mac USB ports (several unanswered questions in the Mini Support forums here involving USB and peripherals, I noticed), what else would explain the seemingly short lives of USB hubs?
Oh, here's something I just remembered: the last time the Belkin hub was working (last night), I had my Radtech BT mouse charger cable plugged in (not charging, mouse not attached) along with two of the external hard drives, and my Fuji camera USB cable. I got an error message onscreen (on the Mini) that a drive had been improperly ejected (or put away?), yet the hard drive in question was still mounted on the desktop. I looked at the hub, and the loose ends of the charger and the camera USB cable were touching. Could that have caused the error (and maybe the hub to fail)? (Edit: the camera cable I think was plugged into the mini's one available port; 3 external drives and the mouse charger were plugged into the hub, _but only one drive powered up and in use (3rd edit)_. The camera end of its USB cable contacted the mini-plug end of the mouse charger... could that have short-circuited the hub? +That wouldn't explain the failure of the GE hub a couple weeks before... but I don't know if any of this is connected, so to speak--2nd edit.+)

All I can suggeset is:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
or
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
Have you looked at the AMDS topic of:

USB hub and internet sharing stop working after sleep

Hi,
I have a relatively new Bluestork USB hub I purchased to connect multiple USB devices I have at the same time. It used to work correctly under Leopard, but now it stops working each time the computer wakes up from sleep. I have to restart the computer for it to start working again. Both link and power LEDs stay on, even when the hub is not recognized.
My second problem is related to internet sharing. It stops working after each sleep/wakeup cycle and the only way to make it work again is to restart the computer. It used to work correctly before Snow Leopard as well.
I have all the Mac updates installed.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.

Logitech dinovo edge stopped working

It used to work out of the box I just had to run the bluetooth, and it worked.

I was able to get mine listed in hcitool by using hid2hci. Use lsusb to get the device's hex ID (just running the command hid2hci worked as well since I only had one device). I was able to enable this behavior on start by setting HID2HCI_ENABLE and HIDD_ENABLE to true in /etc/rc.d/bluetooth and /etc/conf.d/bluetooth.

Logitech Quickcam Messenger [046d:08f0]

I was extremely surprised when the kernel gave me the illusion of plug and play, using the gspca driver for this device.
Unfortunately the gspca driver only supports the 046d:08da cam with the same name.
It looks like the actual driver to be used is the one at http://mag.cx/messenger/ , which is prepackaged in community under the name qc-usb-messenger.
Unfortunately, despite seemingly detecting everything...

Does a wrong ioctl mean it's not the right driver?
Is it common that devices with the same id are in fact different devices?
Any help is very welcome,
thanks for your time.

Long shot
*Grins* the reason I'm dusty is because I plugged it in the back just incase! No luck though

ATTENTION: Desktop Manager Has stopped working - SOLVED

Hey everyone!
I've finally, finally solved a
problem I've been dealing with for the past month (since updating DM to the
latest version 6.x.35)
I have a BB Bold 9700 with OS 6.0.0.600 ( by the
way the issue is not related to the OS as I had the error prior to getting this
version).
The problem is that when opening DM, everything is fine AS
LONG as I don't connect my phone. As soon as I do, DM crashes with the dreaded
"DM has stopped working" message. I tried literally everything... Browsed many
forums and found onyl questions without answers... Turns out hundreds of BB
users faced the same problem on various BB models. Out of these I can honestly
say, only 2 managed to fix the issue they were facing.
To start with and
to help people identify if my issue is similar to the one they are facing, I'll
paste the issue as shown in :
Rim.Desktop.Exception.log

Now my problem is
that unlike other error logs posted by users on various forums, mine didn't show
what the issue was... There is a gap between the 1st and 2nd lines in the log.
In all error logs I saw, that missing line was supposed to hold details on the
issue. In my case, the "invalid directory name".
I tried
reinstalling DM without success and after seeing that so many people on the web
had given up considering RIM was not taking any action, I joined the club and
even made the decision not to buy the 9900 once it is released.
Finally
today, for some reason while working on resolving an issue in an application I
use at work, I decided to use a tool for trying to solve the DM crash... The
tool is Process Monitor (procmon.exe) and is an AMAZING tool to see exactly what
happens when you run any process (executable or others).
Granted it's
not very accessible and users who don't work in IT might not be familiar with
many terms/features in this tool, but I honestly don't think there is any other
way to identify the problem you're facing in DM.
In my case I noticed in
the captured activity of Process Monitor that there were two "path not found"
issues just before the activity related to writing into the error log started.
The 2 paths were :
F:\BlackBerry\system\Media Sync\xxxxx.system
C:\Users\Nicolas\AppData\Roaming\Research In Motion\BlackBerry Media
Sync\<mypin>.settings
First path is on the blackberry itself
and in my case I had a file named "media sync" but no folder. I renamed that
file and created the folder with that name.
For the 2nd path, which was
very strange, I could not find a file matching my BB pin... There was another
one matching my wife's pin. I just took a copy of it and renamed it to my pin
number.
After these 2 adjustments I reopened DM and I got a message
that a new device had been detected. I did a few settings and my BB connected
successfully... No crash... I tried syncing, backup and everything seems to be
working fine now.
I hope this helps others in investigating the
issues they are facing. By the way in Process Monitor be sure to first access
the Filter options and select process name as : "rim.destop.exe"
This will
monitor ONLY the activity related to DM.

Hi Nicolas81...
Thanks for the detail here. just to let you know, we have logged a bug with the Desktop Manager development team to have this fixed for the next version.
Cheers

Logitech Touchmouse app stopped working

My Logitech Touchmouse iPhone app has stopped working. When run from the iPhone, says Searching for Servers and never comes back. Entering IP address by hand says Cannot Connect. Turning off Firewall does not help. Server is running on my Mac. iOS 4 and 10.6.4 on an iMac. Was working before iOS 4 upgrade for sure.
Anyone else?

I was able to get mine listed in hcitool by using hid2hci. Use lsusb to get the device's hex ID (just running the command hid2hci worked as well since I only had one device). I was able to enable this behavior on start by setting HID2HCI_ENABLE and HIDD_ENABLE to true in /etc/rc.d/bluetooth and /etc/conf.d/bluetooth.
