Windows 7: Consistent 0x7E BSOD with lvrs64.sys

Consistent 0x7E BSOD with lvrs64.sys

Hey everyone,

I am making this topic for my girlfriend, who has been having this problem for a while now. We're not sure when it started, but my own research online (which should be taken with a grain of salt) says it has something to do with logitech, presumably her webcam. The webcam we had at the time has been confirmed to be incompatible with windows 7, so we removed the drivers, threw away the cam and got a new one, for which we installed the appropriate drivers. The problem persists.

The problem is an occasional BSOD, of which we've taken these pictures. I've also included the zip file you guys need. It happens seemingly at random, but the error is always the same.

I hope you guys can figure this out.

Hi SeanHL,

The research seems to be correct, the cause is the Logitech Webcam driver, which looks quite old.
Could you let me know where you got the drivers?
Code:
1: kd> lmvm lvrs64
Browse full module list
start             end                 module name
fffff880`05f9c000 fffff880`05ff0000   lvrs64   T (no symbols)

I got it from here:

HD Webcam C270 - Logitech Support

I have the same webcam, but it hasn't caused a bluescreen yet. I guess i should wait and see if it happens to me too. Would suck if we have to switch webcams again.

Unfortunately I cannot access the support page, possibly due to the limited connection here (I'm on vacation)

It's the official site, at any rate. At least for as far as i know. The page does say that the webcam is compatible with windows 7.

EDIT: I've had a dig around the logitech forums, and there's more people complaining about this issue. It's apparently been around for a while:

Although there is no reply within a few days, please have patience. I'm currently on vacation for a week now but will be back home within a few days.

Hi Sean,
buried away in an earlier thread,
logitech webcam instalation problem
When installing the logitech software (1st install) you must select the same language as the OS.

The person in that topic was never experiencing a bluescreen though. We don't have the same problems as he does. Besides, the language is the same for both already, so i'm afraid that's not it.
