Help with firewire (microscope) camera

Hey,
I am trying to use a microscope camera (olympus XC50) on my arch system.

Unfortunately, I get the following:

$ dvgrab
Error: no camera exists

Some potentially useful data:

$ dmesg | grep firewire
firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 4 IR + 8 IT contexts, quirks 0x2
firewire_core 0000:04:00.0: created device fw0: GUID 0001b71100008f57, S400

I have done some web searching and even checked all potentially relevant forum posts (up to 2007) but to no avail. My system is fully up to date.

Thanks in advance.

Try with ffmpeg.
If

 ffmpeg -f iec61883 -i auto 

doesn't return

 iec61883 @ 0x564052fc6540] No AV/C devices found. 

you should be able to use ffmpeg to capture the microscope.

Re: Help with firewire (microscope) camera

Unfortunately that's exactly what happens:

$ ffmpeg -f iec61883 -i auto
ffmpeg version [...]
[iec61883 @ 0x558ade5499c0] No AV/C devices found.
auto: Input/output error

The camera works perfectly on windows; I suspect it could work on linux but it is somehow not recognized as a camera at all.
