Hi, I've run into a really annoying issue on Ubuntu 12.04: the FireWire device files are not created, even though the device is attached and is powered from the FireWire cable. The device is Focusrite Saffire PRO24. $ uname -a Linux darkroom 3.2.0-24-generic-pae #39-Ubuntu SMP Mon May 21 18:54:21 UTC 2012 i686 i686 i386 GNU/Linux $ lspci -k 05:00.0 FireWire (IEEE 1394): Reply Group Device 3044 (rev 46) Subsystem: Reply Group Device 3044 Kernel modules: firewire-ohci $ lsmod | grep -e 1394 -e firewire firewire_ohci 40172 0 firewire_core 56906 1 firewire_ohci crc_itu_t 12627 1 firewire_core However $ ls -l /dev/fw* already says there are no such files or directories, and same for $ grep . /sys/bus/firewire/devices/fw*/*_name Also, $ grep -e 1394 -e firewire /proc/interrupts is silent too I've absolutely no idea whatsoever what could be wrong. The same configuration used to work on the previous version of Ubuntu with a slightly older kernel (not sure about older/newer stack, though). Complete output from ffado-diag is here: http://pastebin.com/iT0cW4bd Alexandre Prokoudine http://libregraphicsworld.org |

One of the PCI data lines is broken. I'm sure this has nothing to do with the Ubuntu version. Regards, Clemens |
