    Ok, there are two separate problems here:

    1. The sysfs intf entry is not created, and this causes the oops later
    when trying to remove the entry, etc.

    I've tracked this problem back to this patch:
    [PATCH] driver core: fix error handling in bus_add_device;a=commit;h=ca2b94ba12f3c36fd3d6ed9d38b3798d4dad0d8b

    Once the patch above is reverted, I have no more oops, my driver can
    be loaded/unloaded just fine, and the /sys/devices/.../ is present.

    However, I'm not really sure if the problem comes from the above
    patch or from my driver which should manually call
    usb_create_sysfs_intf_files() or something equivalent.

    2. There is still a problem with the early loading of the driver. If
    loaded at boot, it won't work. If I rmmod/insmod it later it does.
