Can't find the Crystal Eye Webcam driver for Acer Aspire 5310  

Hello!
I bought a secondhand Acer Aspire 5310 and I reinstalled all the drivers except the driver of the webcam, I found three drivers of the webcam in Acer website I installed them all, but the webcam doesn't work. there's also an unknown device that I don't know what it it.
I'm running Windows 7 professional 32 bits

that's all I have in the Details tab:

UNKNOWN DEVICE
USB/UNKNOWN

when I installed Crystal Eye Webcam driver, it disappeared, and today morning when I turned on the laptop, the driver is gone and the unknown device is back again.

no, I didn't, I'll try now

Did you Install the Chipset Driver from the Acer Website ? ...

nothing new, it's always the same problem.

Right click the Unknown USB device->Uninstall

This could be a long shot but give it a try:
Power down the laptop. Unplug from AC. Remove the battery. Let it sit over night. Then put battery back, plug in, boot up
> Is the web cam detected? Look in DevMgr under Imaging Devices
> Does Unknown USB reappear?
> Or any device entries with yellow icons?

Ok, Thanks, I'll try it now.

Acer uses four different suppliers and this can get very tricky. What drivers have you already tried?

Go to CP / Programs and Features, and uninstall anything to do with the webcam. Then go to Device Manager and unistall anything to do with the webcam ("imaging device"). Reboot. Go back to DM, right-click the imaging device and go to the Properties / Details tab. Select Hardware ID in the drop-down box and read what the "VEN_" spec is.
