[GLLUG] Digital Video Cameras & Linux

[Sean O'Malley]

It has been a while since I worked with fw and no experience with digital
cameras and linux. (I was more interested in IP over firewire and the
speed boost over USB) (there is probably a long winded comment on here
from about 6-7 years ago about it that has more detailed info.)

The Firewire pin outs on cameras are usually just a smaller subset
without the power pins. However there is the 400 and 800 standard and the
pin numbers vary.

IIRC It needs essentially a network address and once it has that a
resource type. My guess is it isn't recognizing the resource type or
negotiating it correctly.

Has the firewire port worked before? I assume yes, but ..

The -best- docs on both USB and FW were from the developer.apple.com
site. Good explanations of both technologies at the detail level of a
developer.

IIRC there was also a sniffer/debugger for linux for FW.
