Linux – Accessing MTP mounted device in terminal

Try out this http://bernaerts.dyndns.org/linux/74-ubuntu/268-ubuntu-automount-any-mtp-device

This guide explains how to easily configure your Ubuntu computer to directly access your Android devices filesystem in MTP mode as soon as you plug it to a USB port. This guide has been completly rewritten to use mtp-detect. It has been tested with a Google Nexus 4 and a Google Nexus 7, but it should work with any other MTP device (Android phone or tablet, MP4 player, ...). It has been done under Ubuntu 12.04 LTS Amd64 but it should work or be easily adapted on many Linux flavours.

Haven't found a way to make the changes permanent yet, but at least there's a way to manually change drivers:

For example with my sony walkman:

• Plug it in and find out its vendor and product id with lsusb:

  # lsusb 
  Bus 001 Device 003: ID 0402:7675 ALi Corp. 
  Bus 001 Device 025: ID 054c:04be Sony Corp. 
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  ...
  

  -> so in this case: 054c 04be.

• Switch it to usb_storage with:

  # mtp_switch 054c 04be
  

It should get mounted automatically (on ubuntu at least)

mtp_switch script:

#!/bin/bash

usage()
{
    echo "Usage: mtp_switch vendor_id product_id"
    echo "  switch usb device driver from mtp to usb storage."
    exit 1
}

[ $# = "2" ] || usage

vendor="$1"
product="$2"

die()
{
    echo "$@"
    exit 1
}

find_bus_id()
{
    cd /sys/bus/usb/devices/
    for f in *:* ; do
    if grep -qi "^usb:v${vendor}p${product}" "$f/modalias" 2>/dev/null; then
        echo $f
        return
    fi
    done
}

driver()
{
    readlink "/sys/bus/usb/devices/$bus_id/driver"
}

bus_id=`find_bus_id`
[ -n "$bus_id" ]         || die "couldn't find device"
driver | grep -q 'usbfs' || die "device's driver is not mtp"

cd "/sys/bus/usb/drivers"
echo -n "Unbinding mtp driver ..."
while driver | grep -q usbfs; do
    echo -n "$bus_id" > usbfs/unbind
    sleep 0.5
done
echo ""

echo -n "$bus_id" > usb-storage/bind
echo "Done."
