Re: [Ipodlinux-devel] firewire success!

[Bernard L. <le...@bo...>]

Hi all,

A couple of points I managed to miss in the announcement.

In order to use the eth1394 module on your host machine I would
currently recommend sticking to just having the PC and iPod connected. 
I don't believe it should cause any problems to other devices but its
very early days in this driver's life :)  The patch to the eth1394
driver renders it pretty much useless for talking to anything but the
iPod.  You can have a 2nd copy of that driver and just modprobe the
correct one if you need a "normal" eth1394 as well.

The second big catch is that the iPod must have nodeid 01 and the host
must be 00.  The two ids are allocated basically randomly so if the iPod
ends up with the wrong one just reboot it.  Hopefully I can sort out
this bug soon!

cheers,
bern.
