DAE error -6006 on launch of Pro Tools M-Powered on Win XP machine. Pro Tools will not launch.

The error means one of the following things happened:
 

• The driver failed to start (i.e. we called start but didn’t get any callbacks for five seconds). If there’s a five second delay before the error message, then this is what’s going on.
• The driver issued an unexpected / unsupported reset request. (That shouldn’t be the case for a FireWire device unless it gets hot-plugged or something.)
• The driver failed to respond to getBufferSize or getSampleRate calls. Again, not likely if the device is otherwise healthy.
   

Most common causes are:
 

• Running Windows XP Service Pack 1. (Update to SP2)
• Incompatible FireWire card/port. (Install a qualified FireWire card)
• Insufficient Bus Power. (See this Knowledge Base article)
   

Here are some tips on further debugging:
 

• Confirm that the device works as expected in some other ASIO application
• Try a different FireWire port and/or cable
• Select some *other* sound device as the default device in the control panel
