HV30 and grabbing in 3.16.0-31

[Elias A. <eli...@ik...>]

Hi,

I am trying to get dvgrab to work in Ubuntu 14.10 running kernel
3.16.0-31. The distro has the "new" FW stack and I have done the tricks
described here:
https://kdenlive.org/user-manual/troubleshooting-and-common-problems/troubleshooting-firewire-capture

I have tested two PCIMCIA adapters:

16:00.0 FireWire (IEEE 1394):16:00.0 FireWire (IEEE 1394): VIA
Technologies, Inc. VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI Controller
(rev 46) VIA Technologies, Inc. VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI
Controller (rev 46)

and 16:00.0 FireWire (IEEE 1394): NEC Corporation uPD72874 [Firewarden]
IEEE1394a OHCI 1.1 Link/3-port PHY Controller (rev 01)

When I plug in the VIA card, syslog says:

The last row looks like it is a no go so let's try the NEC one. Syslog:

So far so good. Now let's plug in Canon HV30 and switch it on.

dvgrab -i
Error: no camera exists

Let's try Ubuntu studio control to enable raw 1394 access. Still no camera.

Eject & replug the PCMCIA card - oops... no changes shown in syslog
anymore....

What should I try next?
