No USB connection - phone not seen!

Just got mine, same issue.  The solution is to plug into a USB 2.0 port, not 3.0 or 3.1.  Downside is you charge very slowly that way.

When you plug into a 3.x it is seen and then this shows up in dmesg:

[955678.668673] usb 8-1: new high-speed USB device number 2 using xhci_hcd

So it is some sort of software issue and not a hardware thing, means it will get better as soon as somebody who deeply understand USB has a look.
