Quickcam Messenger working on Windows Vista / Windows 7 x86
Windows 7 RTM x86
The following hack will use Windows XP driver (a common trick to use non Vista compliant device) to install the webcam in Windows Vista and Windows 7 (x86):
However, with the release of Windows Vista SP1 and Windows 7, the trick comes out with new error. After installing Windows Vista SP1, for some users who have use the XP driver trick to use the unsupported Logitech device, or attempt to install XP driver for Logitech webcam, the following error message will appear:
The device can not be started.
And the microphone attached on the QuickCam no longer works, where the system cannot capture or hear any sound via mic on the webcam (in device manager shown as Logitech Microphone (Messenger)).
Switching to install higher version of drivers does not help either to solve the problem. And thanks to Luis, a workaround solution has been found to fix the error.
It is strongly recommended to Backup your Windows partition (i.e. with Ghost or Acronis) before executing this solution.
The cause of the Logitech QuickCam webcam error on Windows Vista with Service Pack 1 (SP1) is USB audio class driver, USBaudio.sys, which has been updated in SP1. To solve the problem that the Logitech QuickCam Messenger, Zoom, Chat, IM, Express and other unsupported webcam model cannot be used in Windows Vista SP1 and Windows 7, one workaround solution is to ‘downgrade’ the USBaudio.sys driver file located in \Windows\System32\drivers folder to an older version.
However, in normal running computer, the file is always in use, and thus locked and cannot be deleted nor moved while system is running. Use the trick below to copy and swap back to old version of the file.
I don’t know if this solution works also on Windows Vista x64 and Windows 7 x64 systems. I hope someone can verify this.

The 'Add Legacy Hardware' wizard starts (mostly) automatically when you connect your webcam.
If not, you can still manually launch the 'Add Legacy Hardware' Control Panel applet by using hdwwiz.exe.
Start --> Run --> hdwwiz.exe

Installing the drivers running them under XP Service Pack 2 compatibility has made the Quickcam work under Vista. Thanks so much for the tip!
