Yes, I have connected the isight manually under USB. By the way, I re-installed win xp pro over again to be sure - same problem.
I would try manually installing the iSight Driver and to do that you need to manually extract the files out of the setup file...
Directions to extract the iSight Driver from the AppleiSightInstaller.exe file...
On the Leopard DVD, while in Windows, look for AppleiSightInstaller.exe and copy it to its own folder on the hard drive.
Although you cannot execute it by itself however you can use UNRAR to extract the files and then point to that folder when necessary.
At a Command Prompt: unrar x AppleiSightInstaller.exe
Note: The above command assumes the unrar.exe and the AppleiSightInstaller.exe are in the same folder and the Command Prompt is set to that folder.
This will extract the files necessary to manually update the device.
You can get a copy of UNRAR from...
GNU utilities for Win32
http://downloads.sourceforge.net/unxutils/UnxUtils.zip
When extracting the UnxUtils.zip the unrar.exe is at "/UnxUtils/usr/local/wbin/unrar.exe"
Then in the Device Manager select the "Built-in iSight" on the "Others devices" node and right-click and select Properties then on the Driver tab click the Update Driver... button and follow through with the ensuing dialog boxes to manually point to the extracted files folder and update the driver.
