Hi Fernando,
Thanks for the reply.

[Switching to process 504 thread 0xf07]
IOUSBDeviceClass::GetConfigurationDescriptorPtr cache was INVALID
(gdb) p result
$1 = -536870160
(gdb)

List etiquette is to always reply to the complete list and not just to individual people.

This is a kIOReturnNotFound. This is returned when we are unable to get the
configuration descriptor from the device. It looks like we didn't enumerate
this device correctly. What does ioreg -l show for this device?
