So far as documentation is all right, they are not:
=== InterfaceInterface.html ===
...
ReadPipeTO
Note: This function is only available with
IOUSBInterfaceInterface182 and above.
Abstract: Does a read on a BULK IN or an INTERRUPT pipe, specifying
timeout values
...
=== cut here ===
This is true of ReadPipeTO but not WritePipeTO which states:
-----
Note: This function is only available with IOUSBInterfaceInterface182
and above.
Abstract: Does a write on a BULK OUT pipe, specifying timeout values
IOReturn(*WritePipeTO)(void *self, UInt8 pipeRef, void *buf, UInt32
size, UInt32 noDataTimeout, UInt32 *completionTimeout);
-----
Well, I've tried to iterate interfaces using
<snip>
and I got only one interface there. Perhaps I did something improperly?
Looks ok from a brief glance but, like you, I am surprised there is
no bulk pipe :)
