We are attempting to start to architect some new USB 2.0 code, both for PC
and Mac, that will get pictures from Digital Cameras. We also have a "Live
Mode" that tries to achieve a high frame rate.
We have written code for PCI and firewire that will issue several data read
requests at a time, not waiting to get a reply from the first read before we
request the second read. There are several reasons for this, some having to
do with how the camera itself operates it's FIFO.
So my questions is, is this achievable with user space USB 2.0 code on OS X?
I've seen some sample code that does an asynchronous read, then in it's
callback routine issues the next read. But can I issue several reads before
I receive the callback from the first read?
