[Bug 36598] firewire dvd burner fails to coldplug into hal

Sat Mar 25 15:37:44 UTC 2006

Public bug reported:
https://launchpad.net/malone/bugs/36598

Affects: hal (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If I boot my computer with my DVD drive plugged in then HAL fails to
show it in the device list.  I get some sort of a strange 'iLink
interface' that I think represents the Firewire interface on the device
but I get no SCSI stuff.

The modules get loaded properly and I have nodes in /dev.  I can also see it in sysfs here:
/sys/bus/ieee1394/devices/08004609000d626e/08004609000d626e-0/host3/target3:0:0/3:0:0:0

If I powercycle the DVD drive (ie: hotplug) then it works.  The new sysfs path is:
/sys/bus/ieee1394/devices/08004609000d626e/08004609000d626e-0/host7/target7:0:0/7:0:0:0

(ie: same, except for the scsi 'host' number)

I believe this to be a HAL bug because sysfs and devfs both register the
device properly on coldplug.
