Public bug reported: I have added these two rules: #MTP mode: ATTR{idVendor}=="0e79", ATTR{idProduct}=="15ba", SYMLINK+="libmtp-%k", MODE="0660", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1" #PTP mode: ATTR{idVendor}=="0e79", ATTR{idProduct}=="15bc", SYMLINK+="libmtp-%k", MODE="0664", GROUP="plugdev", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1" and it works. The line for PTP mode actually does nothing, the device was created with the same parameters before I added it. I mentioned the line just as an excuse for providing the prod_id.
Package-version: 1.1.6-20-g1b9f164-1ubuntu2 File: /lib/udev/rules.d/69-libmtp.rules Ubuntu 14.04.1 LTS Previously the device only worked in PTP mode while in MTP mode it was silently failing (nothing was actually failing, but the device was created with the wrong attributes, so it didn't work). No device appeared in Nautilus, ADB was saying "insufficient permissions for device". ** Affects: libmtp (Ubuntu) Importance: Undecided Status: New ** Tags: mtp trusty ** Attachment added: "archos_cobalt_lsusb.txt" https://bugs.launchpad.net/bugs/1410177/+attachment/4297183/+files/archos_cobalt_lsusb.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1410177 Title: New USB vendor_id/product_id for ARCHOS Cobalt tablet To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libmtp/+bug/1410177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
