Re: [Ipodlinux-devel] 3g firewire success

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

Hey Daniel,

Thanks for the testing.  I've commited the fix to the iPod firewire
driver now so once the public CVS server is updated (v1.6 has the fix)
only the #define needs to be modified.

On the server side I will see about updating the documentation shortly. 
But basically the host nodemgr.c needs to be patched (commenting out the
do_irm_duties) and the eth1394.c driver replaced with the one from the
ipodlinux CVS (this already contains the patch mentioned in the manual).

cheers,
bern.
