What application are you trying to use the webcam with? This from the Logitech C270 support page
UVC devices work well with native Mac OS applications like Photobooth, iChat, FaceTime HD and QuickTime.

There are only certain Logitech Webcams that work with Macs and OS X.
According to Logitech the webcam you purchased DOES NOT work with Macs or OS X.
Here's the only Logitech Webcam that Logictech states that works with both Macs and PCs.
I have this webcam and can confirm it works pretty well with Macs, but the Logitech software for Mac is more limited than the same software used on a PC.
Some of its stated functions only work on the PC side and not the Mac side.

Also according to the Logitech website "Your Logitech camera must be UVC (Universal Video Class) compliant in order to be used on your Mac OS 10.4.9 or later computer. These standard UVC drivers are provided by the operating system and will only provide minimal camera support".
The C270 is listed as UVC compliant and I'm on OS X 10.6.8.
I'm tried to use it with Photobooth and also Skype but with zero success.

I installed the additional Logitech software and my c615 works fine.
Did you try and install the additional software and use it?
I bought this webcam as it directly said on the packaging that it would work with both Mac and PC.
None of the other Logitech offerings printed this compatibilty on the box.
Leads me to believe that their other offerings are simply not compatible on Macs.

The Logitech HD Webcam C270 works fine with OS X, but you have to install the software before plug it into the USB port. There isn't a native OS X driver for this webcam.
The software (Logitech Webcam Software.mpkg) is in the CD that come in the product box but is not avaiable to download from the website. So if your Mac doesn't have a CD/DVD drive you'll have to use another Mac computer with a CD/DVD drive to copy it to a thumb drive or send it via network or internet to your Mac.

I confirm that too. It works with no problem at all! All you have to do is to insert the CD and install the software (Logitech Webcam Software.mpkg). It also has an update after the installation. Then you plug-in the camera and it is fine. It worked at ML 10.8.2 & 10.8.3!

I bought the Logitech c270 this week and they did not include the CD in the box - the in-box manual refers to a CD, but the side of the box says 'requires software download from Logitech.com.' However, the version of Logitech Webcam Software they have on the site is not compatible with OSX 10.7 and above. So, buyer beware until Logitech sorts it out.

Seems like Logitech finally sorted this one out by providing Mac software.
Here you go:
