I still don't see any lines about the headphone device in the log.  
Was the headphone plugged in during boot, or did you plug it in later?

Here's what your "registers" file says:

This is very bad.  It indicates that the CPU was unable to communicate
with the EHCI controller at all!  All the memory-mapped I/O reads
returned 0xffffffff.  No wonder the keyboard and mouse stopped working.

I have no idea what could have caused this to happen.  Even if the 
controller had suffered a fatal error, you wouldn't see this.  It looks 
like the bus's connection to the controller was turned off.

I'm CC-ing the PS3 maintainer and mailing list.  Maybe people there can 
help.

Those are normal.  They occur because your system loads ohci-hcd before 
ehci-hcd.  It should load ehci-hcd first.

There is a known but yet unfixed bug for the PS3's EHCI Async Periodic
(typically audio recording) device handling.  There are a few related
hardware errata that I have not yet implemented driver fixes for that
I think are causing it.  

I guess it is the same problem as reported by Abhishek since Andrew's
dmesg (http://www.osl.iu.edu/~afriedle/dmesg.txt) shows similar 
results.

More info is here:

  http://ozlabs.org/pipermail/cbe-oss-dev/2009-February/006365.html

I have bought a ART Tube USB device but have not had time to fix
this bug.  It is on my todo list.  Please feel free to make an
attempt.

Alan, thanks for your effort on this so far, sorry you didn't know
about the previous report.

Yes, it definitely looks the same.

Where is the information about the hardware errata you mentioned?

Sorry, I should have mentioned it.  Unfortunately, that info is not
in the public as far as I know.  I think only someone with access
to those will be able to work on this fix.

Okay, then I guess there's nothing more I can do regarding Bug #13304.  
Can you take it over?

Yes, as I mentioned, it is on my to-do list.  I'll bump up the priority
now that there are two users reporting the problem.
