Message:

Automatic pipe sessions

It is no longer necessary to start sessions on USB pipes manually.
Actually, the original functions usb_pipe_start/end_session are now
deprecated.

For sporadic transfers, you do not need to care about sessions at all.
For longer transfers, you may hint the library about it by calling
usb_pipe_start_long_transfer.
