mtpfs, go-mtpfs, gmtp, mtp-detect and nautilus (gvfs, or gio, or whatever) all use the same libmtp library. It seems that the common way to query MTP devices used to be "pull a list of all objects", "push and pull individual objects". A lot of old, legacy devices actually seem to *expect* that kind of behaviour.
When Google decided upon MTP, they obviously just tested with Windows. (The OSX people also tend to mumble and growl about the transfer speed). I have no idea how the Windows MTP stack works: on Windows XP you have to install Windows Media Player, but later versions seem to have it built-in. The rationale being that you don't want people to install third-party stuff, so you stick with whatever crap protocol Microsoft designed. MTP is NOT made for generic file transfer, it's made for "media" transfer (i.e. videos, music and pictures). It's entirely plausible that Microsoft's MTP stack does a per-device check (or uses massive USB id databases) to see whether the devices are "old" or "new" style, and works accordingly. Also Microsoft's MTP stack runs a single service that connects and speaks to the MTP devices, so the way libmtp speaks to the devices is by nature completely different. So, it looks like the two styles (incremental fetching of objects, and full listing) seems to be slightly incompatible. libmtp supports both, but the application using it (go-mtpfs and mtpfs) use entirely different parts of the API, it seems. So, either we need to find out where the code that uses libmtp in Nautilus is built, use *shudder* go (I feel like installing .NET!) or fix mtpfs to use a different style of access. I guess, waiting 10 minutes using gmtp is also an option. Seems like the Ubuntu people are still MIA? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/972311 Title: Accessing a MTP device like the Galaxy Nexus fails Status in “nautilus” package in Ubuntu: Confirmed Bug description: When I connect my Galaxy Nexus to my system (up to date precise) and try to access the data on my phone, I get the following error...
