The Nex contains a number of USB Descriptors, these are all contained in the libusb.so file

These are:

  * PTP
  * MSC (Mass storage)
  * SEN (could be some sort of console access but uses the 0xFF class codes at the interface level. This implies that it is not a simple usb-serial bridge, but a proprietary protocol created by Sony which could make it harder to use as a vector for testing/hacking)

The method for changing modes is currently unknown. If anyone knows how Sony cameras change modes to ptp mode please advise as it will help with working out how the other modes may be accessed
>On the nex-5r you can just select it in menu. Also if you go to the sony appstore you can change the camera to ptp mode by clicking some button on the website. That's also the mode while an app is transfered to the camera. Here's a usbcapture of this {{change_to_ptp_mode.pcap.zip}} In beginning the Device is 35 in Mass storage mode and after change to ptp mode its 36

There are a couple more, will update this page soon with more details.
