Hi,
I want to buy a miniDV camera, transfer the DV stream using firewire.
Now, I'm really newbie on firewire devices and DV, I have none so far,
and I'd really like to test and see it work before throwing out $1000.
I know, this is probably one of those questions that I would answer by
"go try, see if it works" but I'd rather not get embarrased in the shop
trying to get silly permissions or other things right :-)
So, how make sure that I can access the firewire device as ordinary user
and test with gvdrecv, kino or other programs? Do I need to configure
the device as root before I switch to ordinary user privileges? how?
Thanks! Erik
Here's my setup:
Kernel config file:
# FireWire support
device firewire # FireWire bus code
device fwe # Ethernet over FireWire (non-standard!)
#device sbp # SCSI over FireWire (Requires scbus and da)
device fwip # IP over FireWire (rfc2734 and rfc3146)
# dmesg

There's no firewire0 device, but this may be because I have nothing
attached.
