If you did an update that updated the kernel then run
genzaptelconf  and rebuild_zaptel
from root.
The pseudo zap timer uses the usb interface, disabling USB can cause 
issues if you're using pseudo zap.

It might be the dhcp server they bundle too (I don't use the DHCP server).
I did have an issue once where I initially loaded asterisk at home without 
a zap card and then put one in,
I didn't have time to figure it out, so I simply reloaded asterisk at home 
with the card installed and it worked fine.

It will do it automatically.

I don't have cisco hardware either.  Sounds more like the kernel modules 
aren't setup.
Does the box have a sound card?   Asterisk uses the sound card hardware 
for a bunch of things.

True, but if it's not there you can be sure it isn't setup.

Hmm..  What is on irq11 - libata?
Having eth0 and the zap card on the same interrupt will give you all 
sorts of trouble with audio quality.
Go into the bios and force some thing to share an irq or disable thing 
you don't care about

           


Heres from a box I'm building:
[root at asterisk1 root]# cat /proc/interrupts

  0:   53503481          XT-PIC  timer

 I think at this point you should start over. 
This thing has about the same learning curve as Linux does, but like 
Linux persistence pays off :)
I started over about 6 times before I got the first one right after that 
it was much easier. 

Here are some sites that will eat up more time than you have (grin):

    http://www.voip-info.org
    http://voxilla.com
    http://sourceforge.net/forum/?group_id=123387
    http://sourceforge.net/forum/?group_id=121515

It definately looks like the zap module isn't getting loaded start with 
genzaptelconf and rebuild_zaptel .
