>Description:
Any attempt to access my Nikon Coolpix L22 camera through "gphoto2"
hangs without producing any output (or error message).
>How-To-Repeat:
S/A
>Fix:
Workaround for NetBSD:

The following patch was provided by M. Levinson
<mlevins@users.sourceforge.net> in private email:

+--- libgphoto2_port/libusb1/libusb1.c
++++ libgphoto2_port/libusb1/libusb1.c
+@@ -684,6 +684,8 @@ gp_libusb1_queue_interrupt_urbs (GPPort *port)
+ 	unsigned int i;
+ 	int ret = 0;
+ 
++	return 0; /* not working yet */
++
+ 	/* no interrupt endpoint */
+ 	if (port->settings.usb.intep == -1)
+ 		return GP_OK;

With the above patch applied to "devel/libgphoto2", I can access the camera
without problems.  Don't know what the correct solution might be.
