After some testing, I determined that the combination of usbutils (0.70-1) and libusb-0.1-4 (0.1.9-1) on arm results in bogus zero values for bNumInterfaces and the associated *interface pointer winds up null. This same code works fine on x86. Both gphoto2 and ptpcam assume that bNumInterfaces is >=1 and dev->config->interface always points at a valid usb_interface structure, so that would explain their crashing in this case. The lsusb in usbutils (0.9-1) on arm returns the correct values. See battached for a side-by-side diff of output from usbutils lsusb (0.9-1) and usbutils lsusb (0.70-1). Hope this helps. -- Brian Ristuccia [EMAIL PROTECTED]
