It seems we managed to buy a presently unsupported firewire pci card.
I upgraded to the latest -CURRENT and hoped to be lucky, but it seems
that it didn't have to be that easy. :)
This is the dmesg output of the card getting probed:
fwohci0: vendor=1033, dev=e7
fwohci0: <1394 Open Host Controller Interface> mem 0xe0800000-0xe0800fff irq 11 at device 11.0 on pci0
fwohci0: OHCI version 1.10 (ROM=1)
fwohci0: No. of Isochronous channel is 4.
fwohci0: EUI64 00:00:4c:01:07:00:2a:01
fwohci0: Phy 1394a available S400, 2 ports.
fwohci0: Link S400, max_rec 2048 bytes.
fwohci0: FireWire init failed with err=6
device_probe_and_attach: fwohci0 attach returned 5
And this is the information from pciconf -lv:
none2@pci0:11:0: class=0x0c0010 card=0x00ce1033 chip=0x00e71033 rev=0x01 hdr=0x00
vendor = 'NEC Electronics Hong Kong'
device = 'uPD72873 IEEE1394 OHCI 1.1 2-port PHY-Link Ctrlr'
class = serial bus
subclass = FireWire
Based on that, I tried to make the following change:

The dmesg output then changes to this:

fwohci0: OHCI version 1.10 (ROM=1)

As I do not know much about firewire internals I'm not sure how to proceed from
here.
Are there any hopes of getting this card working?
Thanks in advance.
