I, too, purchased the DG03 from DiveGearExpress in May. If you check again now, all the DG03's they are selling off have been upgraded with the new version of firmware (1B). I followed the instructions from the Hollis website and contacted the nearest dive shop that offered service for Hollis equipment. I was told that they (the dive shop) would only send it to Alberta and that I would need to foot the shipping costs. As a result, I contacted Hollis directly stating that I didn't see the fairness in having to pay the shipping and gently suggested that they should pay, or offer me the cable. I finished by simply saying that I was hoping that Hollis would support those of us who have supported them.
After a few brief (and good-spirited) emails back and forth, I was asked for my contact info so that they can send me a USB cable.
It was nice to see that they are willing to support those of us who have invested in their tech.
P.S. I did inform them that my DC was registered through their website and I provided the Serial Number for them during this process.
If you're in a bind with your DG03, contact them and see if they will support you. BTW - neither contact number on the email I received seemed to work. I made initial contact through responding to the emailI received about the pressure issue.
Hope this helps.
