USB device not found using fdisk

Question

I have a new USB device but I cannot see it usign fdisk command. Here below some useful info.

xxx:~$ uname -a
Linux xxx-laptop 3.2.0-67-generic-pae #101-Ubuntu SMP Tue Jul 15 18:04:54 UTC 2014 i686 athlon i386 GNU/Linux

This is the dmesg when I connect the device

[ 5025.592149] usb 1-1: new high-speed USB device number 14 using ehci_hcd

This is the dmesg when I disconnect the device

[ 5076.490468] hub 1-0:1.0: port 1 disabled by hub (EMI?), re-enabling...
[ 5076.490493] usb 1-1: USB disconnect, device number 14

This is the device when I type lsusb

Bus 001 Device 017: ID 05c6:6764 Qualcomm, Inc. 

I have tried to add a new rule into /lib/udev/rules.d/69-libmtp.rules

ATTR{idVendor}=="05c6", ATTR{idProduct}=="6764", SYMLINK+="libmtp-%k", MODE="666", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"

What shall I do?

Thank you

I am not sure the solution proposed applies to OnePlusOne (I assume your case is about this smartphone from the tags). I am giving advice using android 4.2

First, in Settings-->Other first check that you have no Usb tethering option set Then, in Settings-->Memory tap on the three dots upper right, so you can choose if your device is presenting itself using either MTP or PTP. I would guess you won't find any of these two option checked
