1. i am writing a new USB class driver for MTP devices. But when i plug-in the device it is atomatically recognised with mass storage module taking the interface information. But the string descriptor defined as MTP, so how i can lead my class driver to probe the device before usb_stroage module picks.
2. How USB plugin event in class driver can be passed to userspace. So that my MTp library application can understand asynchronoously that device been pluged in. Example if i connect iPod in Linux system it gets recognised by rhytom box application immediately. How come rythmbox able to know that a media player device pluged in.
thanks

adds the ability to not match a MTP device such as your own.
Do you have a pointer to your driver anywhere?
