Over the past few months I've been trying to resolve a webcam problem on a friends PC. The PC is an Acer Aspire 5920 laptop with internal USB Crystal Eye webcam(?), the OS is Vista Home Premium.
The webcam has worked but not very often and at the moment not at all. Device manager shows the cam as:-
Properties -> General: Unknown Device
Device type: Universal Serial Bus Controllers
Manufacturer: (Standard USB Host Controller)
Device staus: No drivers are installed for this device.
Details: Device Instance Path: USB\VID_0000&PID_0000\5&2BE3BD0&0&2.
I've tried several things to resolve the issue including the following:
- disabling/re-enabling the device through Device Manager.
- disabling/re-enabling the USB Root Hub through Device Manager.
- disabling/re-enabling the Host Controller through Device Manager.
- disabling/re-enabling all USB devices, Root Hubs and Host Controllers.
- uninstalling/reinstalling the device through Device Manager.
- uninstalling/reinstalling the USB Root Hub through Device Manager.
- uninstalling/reinstalling the Host Controller through Device Manager.
- uninstalling/reinstalling all USB devices, Root Hubs and Host Controllers.
- uninstalling/reinstalling Crystal Eye application
- reinstalling the driver(s)
- updating the driver(s)
When I manually select the installion driver inf file (snp2uvc.inf) the installer tells me that "Windows has determined the driver software for your device is up to date".
From Google searching, it would appear Acer laptops seem to suffer from sudden loss of webcam but I have yet to find a fix. I found one site that suggested booting the lappy with Ubuntu from a USB stick then check to see if the webcam appeared in that OK. I've managed to boot the laptop with Ubuntu but that's as far as I've got coz I've not used it before and I need to learn how to drive it.
Any help would be much appreciated.
