[clug] MTP and Python - any ideas?

[Paul Wayper]

Hi all,

Is anyone familiar with using libmtp to interface with MTP devices?  I'm
trying to write a program to get some information from my phone, but while the
kernel's usbfs module seems quiet happy to see the phone's file systems and
MATE's file manager can browse the device, my simple "get the device name and
free space" program doesn't get much further than the attempting to connect.

The program is:

#!/usr/bin/python

import pymtp

# Connect to MTP
mtp = pymtp.MTP()
mtp.connect()

# Show a bit of data about the connection
print "Device name:", mtp.get_devicename()
print "Space:", mtp.get_freespace(), "of", mtp.get_totalspace(), "bytes free"

But I get either:

$ python phontosync.py
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
ignoring libusb_claim_interface() = -6PTP_ERROR_IO: failed to open session,
trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
inep: usb_get_endpoint_status(): Resource temporarily unavailable
outep: usb_get_endpoint_status(): Device or resource busy
ignoring libusb_claim_interface() = -6LIBMTP PANIC: failed to open session on
second attempt
Traceback (most recent call last):
  File "phontosync.py", line 7, in <module>
    mtp.connect()
  File "/usr/lib64/python2.7/site-packages/pymtp.py", line 514, in connect
    raise NoDeviceConnected
pymtp.NoDeviceConnected

or:

$ python phontosync.py
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
ignoring libusb_claim_interface() = -6PTP_ERROR_IO: failed to open session,
trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt
Traceback (most recent call last):
  File "phontosync.py", line 7, in <module>
    mtp.connect()
  File "/usr/lib64/python2.7/site-packages/pymtp.py", line 514, in connect
    raise NoDeviceConnected
pymtp.NoDeviceConnected

(Not sure why I get the two different messages.)

Any ideas?

Thanks in advance,

Paul
