Description of problem: mtp-lib fails to detect MTP player - used to work in Fedora-10 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Plugin MTP music player (Cowon D2 in this case) 2. Observe it mounts correctly as a USB device. 3. Fire up Gnomad-2 4. Observe that it unmounts the USB device and attempts to connect. Actual results: It continues to attempt to connect. This goes on forever (until force-terminated). Expected results: Should be able to connect to MTP player and allow adding/removing media files, manipulating play-lists etc. Additional info: Tried using mtp-detect to check if that works. Doesn't work. Tried this as root as well (both mtp-detect and gnomad-2) - doesn't work. So it's definitely nothing to do with permissions.
Have you tried downgrading to libmtp 0.3.7 to see if this is really a regression in libmtp? I think this is rather caused by other apps hogging the player first. Have you tried this, as root # rmmod usb_storage && mtp-detect
Thanks for the tip. Currently, due to a recent X/GDM upgrade (regression), I can't login to a desktop anymore. As soon as I can get something working, I will try this.
I've tried it (# rmmod usb_storage && mtp-detect) as root with the exact same results.

Well perhaps a deeper test: can you disable the desktop and X by (in a console window) init 4 Then insert device, rmmod usb_storage && mtp-detect What I want to know is if there is one of the daemons like gphotofs in Gnome that is stealing the device for you.
Same results - no joy. Here's the steps I followed: 1. Log out of X (Gnome session - no KDE installed anyway). 2. Cntrl-Alt-F2 - on to a CLI, log in as myself 3. su - 4. init 4 5. Log in as myself again 6. su - 7. rmmod usb_storage && mtp-detect Wait for 5 minutes, then Cntrl-C because it's still not doing anything.
Works in Fedora-12. Tested yesterday. mtp-detect and Gnomad-2 work. RhythmBox still doesn't do anything beyond listing music on the MTP-device - but I suppose that's a known issue.
Please close this - it's fixed in F-12.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
