Which one to use — "support" or "sports"?

The first one should read supports, not support. Also, support doesn't really make sense in the context you gave: when talking about devices, to support means to have the ability to use something with the device, but to sport means simply to have a feature.

For example, my netbook sports (has) USB connectors, therefore it supports USB devices.

The word that works here is "sports" and it means the same as "features" would in

Nokia n8 Mobile features a 12-megapixel camera.

It might also support such a camera, but that is not the intent of the copywriter or reviewer in such a case.
