RE: [avrdude-dev] Time Problem Avrdude 5.3.1 on mac

[Yannick PODGORSKI]

Hi,
Thanks for answer.

My configuration :
  - Mac OS X V10.4.8
  - avrdude 5.3.1
  - libusb-0.1.12

I try to find where is the problem. I go to this part of code in file darwin.c 
in libusb-0.1.12 (line 851).

   if (result == kIOReturnSuccess) {
     /* wait for write to complete */
     if (CFRunLoopRunInMode(kCFRunLoopDefaultMode, (timeout+999)/ 1000, true) 
== kCFRunLoopRunTimedOut) {
       (*(device->interface))->AbortPipe(device->interface, pipeRef);
       CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, true); /* Pick up aborted 
callback */
       if (usb_debug)
         fprintf(stderr, "usb_bulk_read: input timed out\n");
     }
   }

The problem seems to be in the code :
if (CFRunLoopRunInMode(kCFRunLoopDefaultMode, (timeout+999)/1000,
true) == kCFRunLoopRunTimedOut)

The program takes 10 seconds in the CFRunLoopRunInMode function.
I don't know where this function is.

Thanks for help.

It performs a couple of libusb operations at that point:

  if (usb_set_configuration(udev, dev->config[0].bConfigurationValue))
    {
      fprintf(stderr,
              "%s: usbdev_open(): error setting configuration %d: %s\n",
              progname, dev->config[0].bConfigurationValue,
              usb_strerror());
      goto trynext;
    }

  usb_interface = dev->config[0].interface[0].altsetting[0].bInterfaceNumber;
  if (usb_claim_interface(udev, usb_interface))
    {
      fprintf(stderr,
              "%s: usbdev_open(): error claiming interface %d: %s\n",
              progname, usb_interface, usb_strerror());
      goto trynext;
    }

  fd->pfd = udev;
  return;
