Not bad...? Isn't the max 1000 USB frames per second? ;) >of about 70 bytes per IRP submission.

I need to put back in recycling of the LinuxRequest objects (not difficult but hadn't got to it yet). I'll check for leaks too, could be in the Linux implementation. >There is no way to set automatic resubmission in this API >so whenever I get a data event on a listener I got to check >all IRPs that were submitted to the iso pipe if they is a >completed one to submit it again. Older API with >setResubmit(true) looked better. resbumit may have been nice but the implementation of it went way beyond a nightmare. I'm assuming you're using the List submission methods (I hope, as it should greatly increase performance on Linux ISO) so why don't you just check the last UsbIrp for each List, and if it's complete, resubmit the entire List, or handle it however else you like. The new API (0.10) includes a getUsbIrp field in UsbPipeDataEvent, as well as allowing user-created UsbIrps (and I'm going to put in a default implementation to extend) which you can override the complete() method. In that you can resubmit the whole batch or do whatever. >I'll try to get a real picture and see how well control >pipe behaves in more detail. great!
