Mac Forum / General / Hardware / June 2006USB controller and driver for iSight inside iMac(G5)?
Hello! I'm having some problems with very low frame rates with my USB-connected webcam on my Mac Mini. The camera is a XA-040 (from X-Tensions) which uses a Sonix SN9C102 controller. I just found out that the iSight webcam built into the G5 iMac is connected via the USB-port internally - so there should be a USB webcam driver residing somewhere inside Mac OSX. Depending on the USB controller Apple uses in these USB webcams, perhaps other 3rd party webcams (with the same controller) could utilize these drivers as well?! So, here's my question: Which USB controller is used by the iMac's iSight? Where could the driver be residing inside MacOSX? I'd be thankful for any hints! Bye, Torge.

I'd look in the usual place, the USB family in the extensions folder: /System/Library/Extensions/IOUSBFamily.kext If you look in there you can find a likely candidate: Contents/PlugIns/AppleUSBVideoSupport.kext IOXperts will sell you a web cam driver. <http://ioxperts.com>, it works with a wide variety of cameras.

Hi Barry, and thanks for your answer to my posting! > > Where could the driver be residing inside MacOSX? > [quoted text clipped - 5 lines] > > Contents/PlugIns/AppleUSBVideoSupport.kext Okay, found that one. Had a look inside the Info.plist, but I only found the vendor to be Apple (id 1452) and the product id to be 33536. I thought, by having a look inside the driver, I could find something like a hint on a standard webcam controller. But it looks like I'll have to wait on someone with insider information (or someone who was able to read something written on the controller itself). > IOXperts will sell you a web cam driver. <http://ioxperts.com>, it > works with a wide variety of cameras. I DO have a working driver for my cam - and the IOXperts driver does not seem to support my webcam (or other models I know of having the same controller: the Macally IceCam, the Genius WebCAM Eye, the D-Link DSB-C110 or the RadioShack DigiGr8 (v2)).

No. The driver not only has to understand USB, it has to understand how to access the iSight hardware. It's unlikely that a driver for the iSight will also work with your camera. Simon.

I can't imagine that Apple would develop a completely new webcam controller for a piece of hardware like that. I would think that they'd use a somewhat standard controller - possibly adjusted to their individual needs at some extent. Bye, Torge.
