Hi,
I wanted to share a problem that I had (and solved) with the digi 003 firewire.
I have digi 003 and pro-tools 10, running on a HP laptop 8460w with built-in firewire.
At some point the pro tools didn't recognize the digi 003, it said that it could not find the hardware.
I had lots of stuff installed on my laptop so I thought I messed something up in windows and the drivers etc.
I started a clean image on windows 7, installed pro tools and the digi 003 drivers and it worked fine.
Then I installed lots of more stuff and it again - the digi 003 was not recognized.
Again I got back to a clean windows 7, and installed everything and sometimes it worked fine and sometimes it didn't recognize the 003 at all.
it drove me crazy, I thought that something wasn't good in the cable or hardware (firewire)... replaced the firewire cable... re-installed everyhing...
To make the story short - I read somewhere that there might be something with the grounding of the electricity.
I then tried disconnecting the laptop from the power adaptor - pro tools found the 003. I reconnected the power adaptor - and pro tools could not connect to the 003.
The power charger I was using at this room (my studio) is a cheap one from ebay, not the original HP.
I then tried the original charger and all worked fine.
Conclusion - the cheap power charger probably didn't have the electricity grounding done right... and this caused the firewire not to work fine.
So if your digi 003 is not recognized - try dis-connecting from the power charger and see if this helps.
Otherwise - make sure you install the 003 drivers of-course.
Hope it helps someone
