Do you have root access? If not, you cannot see anything inside /dev.

yes

Did you get any "avc denied"-message in logcat?

1. Connect your smartphone via USB to your PC/Laptop.
2. Check output of dmesg on your PC/Laptop. It should report something like:

   [136357.754901] usb 2-1: new high-speed USB device number 21 using xhci_hcd
   [136357.895874] usb 2-1: New USB device found, idVendor=18d1, idProduct=4ee7

   If you don't get a dmesg-message like that, there must either be some USB connection problem; or your phone does not get recognized correctly.
