Make automounting work through hal/gnome-mount

Reported by Matt Colyer | March 24th, 2009 @ 03:21 AM | in 1.0 Release

So I attempted to do this before. The trick is that you need the iPhone to enumerate in configuration 3 otherwise it will confuse gnome-mount when you change configuration as it is trying to mount the device.

I had a brief email exchange with Greg KH who suggested:

There is a sysfs file that you can write to to change the config, right? So, from a udev rule, run a script that writes to that file.

Instead of my silly iphone-module solution (a kernel driver which just forces the device to configuration 3)

    echo 3 > /sys/devices/pci0000:00/0000:00:1d.7/usb8/8-3/bConfigurationValue

    Seems to do the trick (as root)

    I have a udev for usbmuxd starting/stopping that I was about to transfer across to doing this.

    It turns out that as libusb uses RAW usb socket access, if the configuration is changed then the kernel sysfs and udev tree because out of sync.


    should be what's necessary from udev. Then a second rule can match on the appearance of endpoints 4/85 and start usbmuxd, then (to be worked out), ifuse needs to start on the basis of /var/run/usbmuxd appearing.

    For reference, the Launchpad bug regarding the out-of-syncness:

    "sync libusb usb_set_configuration() + sysfs .../bConfigurationValue" http://launchpad.net/bugs/347405

    My first stab at this, the FDI file now needs to be modified to match this.

    Ohh I like your solution much better Paul.

    I didn't see it until I committed, I'll go ahead and back out the script and use your command instead. It will probably be later though.

    ATTR{idVendor}!="05ac", GOTO="usbmuxd_rules_end"
    # If it's plug insertion, flip it into dual "PTP + Apple Mobile Device" configuration
    # This allows another application to switch it later without it getting switched back (hopefully)
    # TODO: check iPod Touch/3G
    SUBSYSTEM=="usb", ACTION=="add", ATTR{product}=="iPhone", ATTR{bConfigurationValue}!="3", ATTR{bConfigurationValue}="3", GOTO="usbmuxd_rules_end"

    Is what I currently have here. The rest loads/unloads usbmuxd etc.

    Gah, bug tracker, why will it not just display text as normal fixed with text.

    Committed the fix for using udev instead of the script. I am thinking that iFuse should still be set to automount through the gnome-mount stuff (through hal).

    When usbmux is integrated, ifuse can poll to see if the daemon is up or start it if it isn't running.

    • State changed from “new” to “resolved”

    I just committed a fully working implementation of automounting. However the github integration was broken from changing urls. That should be fixed up now.
