Q:

Android USB Connection Not Working

I can't seem to connect my Samsung Galaxy Note II (N7100) to my Windows 8 Machine (aiming to use the phone for debugging - but current can't even connect the device as mass storage). No USB notification is shown when connecting the mobile by cable. 
Things I have checked thus far: 
USB Cable (works on different machine and with HTC phone)
USB Ports (tried different ports, 2.0 and 3.0, all working)
PC USB Drivers
Phone (connects to my Win 7 machine)
Samsung Kies (and Samsung driver) and Google USB Driver both installed
PS. The reason Im asking this here is because I'm aiming to use the phone for development and I'm hoping to get some answers that aren't "have you double checked the cable?" like on every Google search I have performed so far. Hopefully another developer recognises this issue.

A:

OK. so You've obviously done the basics and made sure all the cabling is functional.
it sounds like the Volume is not mounting in windows 8
if it's not detected in Windows Device Manager, and More importantly, if it's not visible in Disk Management, then the volume simply is not Mounting.
I would suggest

Try connecting to a Windows 7 Machine and see if it works, if it does, Then Most likely you need Windows 8 Drivers
I would be contacting Samsung Engineers for support on the Issue
What version of Kies are you using
i found this that might be useful for you

Ultimately, as you know the volume is not mounting due to Driver issues, and this needs to be resolved if you are to have a solution

You could always Try setting up XP Mode in Windows 8 and see if it recognizes that way.
Granted this is a bit of a workaround and a bit stuffy, but. Hey,  it's another option.

let me know how you go
