need help on mtp config

[Li Wei <rootof3@yahoo.com>]

I have Samsung GT-S7572 cell phone
and connect to debian by usb line, lsusb:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 004: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-P7500 [Galaxy Tab 10.1]

then I run mtp-detect as root:

Device 0 (VID=04e8 and PID=6860) is a Samsung GT P7310/P7510/N7000/I9070/I9100/I9300 Galaxy Tab 7.7/10.1/S2/S3/Nexus/Note/Y.
