I've been doing some Android development but the virtual testing environment is too slow for me and oftentimes doesn't work at all. I have a Samsung Galaxy Player (Model YP-G1) and I've searched Google as well as Samsung's driver website for my device and I can't find any drivers that will allow me to test Apps I develop in Eclipse on my Galaxy Player. Samsung's site only has one driver, which is apparently something to aid in the syncing of music with the computer.
Even though this question is a bit outdated I stumbled upon it in my quest to find drivers for the Samsung Galaxy S4.
The Samsung development drivers can be downloaded here (notice the spelling mistake in the url but at the moment of writing this is the actual link!):
