Hello,
I tried to use a firewire camera on my desktop but failed.

Here is what I use:
*Debian lenny 2.6.26-1-686
*libraw1394-2.0.5
*libdc1394-2.1.2

Here are the results when I use the following commands.
@ lsmod |grep video1394
video1394              13372  0
ohci1394               24944  1 video1394
ieee1394               75800  3 raw1394,video1394,ohci1394

 @ls -al /dev/raw1394

The libraw1394 works well. The PCI card can be recognized when run the testlibraw under libraw1394/tools.
current generation number: 1

  - posting 0xdeadbeef as an echo request
    polling for leftover messages
    raw1394_loop_iterate() returned 0xdeadbeef

But when I run dc1394_reset_bus under libdc1394/examples, error message shows
"libdc1394 error: Failed to initialize libdc1394".

Does anyone have any idea about how to fix this problem? Thanks a lot.
