Before I connect the camera, I can see the following in dmesg: [ +0.143613] firewire_ohci 0000:05:04.0: added OHCI v1.10 device as card 0, 4 IR + 8 IT contexts, quirks 0x11 [ +0.077028] firewire_core 0000:05:04.0: created device fw0: GUID 0010dc000108f949, S400 I can also see that /dev/fw0 exists. I understand this is just a controller, not a connected device. Upon connecting and turning on the camera, I can see no new output in dmesg. The only new output I can generate with the camera reads: [Jul30 17:25] firewire_core 0000:05:04.0: rediscovered device fw0 which appears when I disconnect the camera (or power it off). dvgrab reports "no camera exists". It is not a permissions problem as I have set open permissions on /dev/fw0 manually. The camera is Sony DCR-TRV320E with a 4 pin FireWire outlet which I connect to the computer's 6 pin one (this shouldn't be relevant). It used to work on the same computer when it was running Windows a long time ago. I also briefly tried it with Linux Mint (also some time ago) and I didn't get it working, but at the time I didn't really look into it too much so it's possible it was just a permissions issue.
