Galaxy S6 not seen by pc at all I have one week old S6 and now tried to use adb. 

I unlocked developer mode, enabled USB debugging, connected to usb and nothing happened. adb devices shows empty list, lsusb on mac and linux as well as mac's "system information" app doesn't see any new usb device when I connect the phone. Nothing happens in dmesg too.

The phone displays "charger connected" notification. No mtp/ptp notification appears.

I tried to use different computers (two linux boxes and one macbook), different cables, nothing. Other android devices (such as old note2 and some noname stuff) works well.

I tried also other person's S6. Result it the same so I don't think it is some kind of damaged socket or so on.

What's going on? Am I missing something? Maybe some security setting prevents USB from working?

UPD

This doesn't look as a "driver" issue at all. lsusb shows all usb devices even if the system doesn't know how to deal with them.
I was getting very frustrated with my Samsung Galaxy S6 and my new Dell Precision M3800 and USB connectivity. Apparently the S6 is not fully compatible with USB 3 connections. I could not get it to connect (other than charging) to any of the 3 USB 3 ports on my laptop (no usb 2 on the new Dell). It connects fine to my older laptop (USB 2), so I decided to try connecting a USB 2 hub to my new Dell and the phone to the hub, and it works!
So, Samsung, please fix this!
