Ok, I have v3.01 or something, so this might indeed make a difference. 
Unfortunatley I didn't note when I updated my POD, so I can't verify if I 
changed the startup procedure roughly at the same time. Nevertheless, please 
*don't* upgrade right now since I believe this isn't too hard to fix.

I'd like to see the messages exchanged on your system. Can please do the 
following:
*) enter "make xconfig" in the svn working copy of the Line6 driver sources
*) open the Line6 driver options (menu "Edit->Find...", then enter "line6")
*) select "dump control messages"
*) save the configuration, compile and install the new Line6 kernel module

The system log should now contain all relevant messages sent to and received 
from the device. You said that you observed periodic requests, so could you 
please extract all lines from the syslog from loading the new driver until the 
periodic message has appeared several times, and send this to me?

	Thanks & kind regards,
		Markus


P.S.: I forward this message to the Line6 mailing list since a similar issue 
(driver module loaded, but no audio I/O) has just been raised there, so others 
might benefit as well if we find a solution. May I suggest that you subscribe 
to this list, and we continue the discussion on the mailing list? Here is the
