I searched for similar questions on this issue but found none related to Mac OSX.
Situation:
Trying to test android apps on a Galaxy S (Details below) but Mac is not detecting the device. Tried all the things below and have wondered whether this might be a driver issue (which I've heard things about for Samsung USB debugging).
Questions:
1) Are samsung drivers required for android USB debugging?
2) And are they available for Mac OSX?
3) Any other reasons OSX might not detect device for usb debugging?
Things I tried:
Using:
Samsung Galaxy S (4G) with Sprint
Mac OSX 10.6.8
Eclipse Classic 3.7.1
Have you tried connecting the phone using a powered USB hub? I haven't tried it yet but found this blog post that suggests it may help for Samsung Galaxy devices.
