Webcam: logitech pro 5000 - BSOD

Just received new Dimension 5150 (2 * 2.8Ghz).

When installing the latest Logitech Pro 5000 webcam drivers, ended up with blue screen in

STOP 0x0000008E (0xc0000005, 0xa7a42636,0xa95bfaf8,0x00000000)
lvckap.sys - Address A7a42636 base at a7a33000, datestamp 43950596

this driver is apparently an audio filter driver (maybe related to the echo cancellation feature?).

I renamed the driver file in safe mode, and the PC boots up, and webcam does still work which is something.

However same sw installed on another non-dell PC is working fine.

Conflict with the creative audio software perhaps?

Comments, suggestions? Anyone else tried same?

Apparently there is also a later version of this file (min is December 2005). Anyone know of another driver/package containing a later one I could try?

I'll probably try contacting logitech at some point, but interesting it's only happened on the dell?

    Best thing is contact Logitech, they may already have a fix for this problem (and it is Logitech's - it's not Dell or Microsoft).

    Hi,

    It may be just a coincidence that you got the BSOD while installing the Logitech drivers as the STOP error 0x0000008E discusses Memory issues. As seen on the forum, there are new systems that come up with this error as the cards are not seated correctly in their slots. Just reseating the memory cards should help...

    Regards

    AJ

    I vaguely remember how to get more detailed info from XP relating to the dump.. I could look at doing this (install symbols, debugger etc).

    Called logitech. They answered real quick, but mostly just did searches against the FAQ. Suspicions of dual core issue, but once I mentioned Media Center Edition they stated this is currently not supported, there is a problem, and I should keep an eye out for new drivers ....

    Also seems all the webcams have the qc950enu.exe drivers. At least I can use the webcam by just renaming the lvckap.sys file, but I need to check audio quality -- I think this aids in echo cancellation (probably by examining the sound the audio card is pumping out the speakers - hence why it's a filter).. so wonder if rather than MCE we could have a compatability problem with Creative Audoligy software?

    In fact searching on google suggests it could indeed be audigy at fault... lots of reports of other filter drivers failing?

    I'll check versions tonight & checkout the creative website (presumably it's ok to try) or try disabling "whatever the extra creative stuff over and above basic sound card support"
    Frustrating.

    Be careful with the Retail SoundBlaster drivers.  The SoundBlasters that Dell supplies is a custom version made only for Dell and needs Dell drivers for some of the extra features (and some of the Retail features are not in the Dell OEM Version cards/modules).

    With most Dell OEM SoundBlaster sound cards/modules if you try to install the Retail drivers the driver install program will not find a SoundBlaster product.

    Here's what I posted to the Logitech forum as my solution:
     
    Hey folks,

    I wanted to share a workaround that has worked for me thus far. I'm not sure if other's have discovered this workaround but this is what I did.

    I had read somewhere that it's the conflict w/the SigmaTel Drivers & the Logitech lvckap.sys drivers, so here's what I did:

    (1) Disabled the SigmaTel audio drivers thru the Hardware's Device Manager (control Panel -> System). This will disable sound on the PC.
    (2) Not sure if this was necessary but I rebooted the PC
    (3) My Logitech software & drivers were already installed. I plugged in my Logitech Webcam
    (4) Voila!!!! No BSOD. I believe that the issue is during the initial phase that Windows discovers the device.

    (5)  Re-enabled SigmaTel soundcard/drivers via Control Panel (corrected/missing statement)
    (6) I ran Skype & Yahoo's IM just fine.
    (7) For grins & giggles, I rebooted the PC to determine if the settings would hold or if I would have to do this everytime I wanted to use the webcam. Everything worked fine w/out incident. So, it appears that this is a one time fix that holds.

    I hope this helps others.

    T

    I had the same issue with Dell 5150 and Logitech webcam 5000. Logitech, Creative, and Dell's forums ALL have people complaining they don't work together and ALL 3 vendors are pointing fingers at each other. As usual, Dell recommended I do a PC restore (the default answer when nothing else works) on my new E510 (Dimension 5150) that is less than two weeks old. When I threw a fit, the best solution a Dell Rep could give me was to send my camera back and get a Creative Labs camera. I am going to try that and see if it works any better. Apparently no one at any of the sites seems to care about this issue, I guess once you have bought the product, it becomes YOUR problem, not the vendor's problem.

    Yes, that is definitely the problem. I searched for weeks for a solution and all three vendors (Creative, Logitech, and Dell) pointed fingers at each other as being the cause. Creative suggested I buy a Creative Webcam instead. What did I have to lose? So I got a Creative webcam and...PRESTO...it works and the problem went away. Of course this was AFTER a Dell Rep had me WIPE OUT my restore partition so I have now lost all the programs that came with my system. So my suggestion would be to return the Logitech and get a Creative cam if you have Creative sound software.
