** Description changed:
My philips MCE USB receiver (mceusb device) does not work with Lirc.
System is ubuntu 12.04-mini.
Running irw does nothing, running it a second time gives "Connection
refused".
xbmc@Media-PC:~$ irw
xbmc@Media-PC:~$ irw
connect: Connection refused
- After the first irw, lirc is already 'hanging'! Restarting the lirc service
will hang the terminal which you will try to run it from, sudo dpkg-reconfigure
lirc will also hang the terminal plus give a dpkg-configure -a error on next
boot.
+ After the first irw, lirc is already 'hanging'! Restarting the lirc service
at this point will hang the terminal which you will try to run it from.
+ Sudo dpkg-reconfigure lirc will also hang the terminal plus give a
dpkg-configure -a error on next boot.
On reboot the system will hang as well, only option being REISUB.
syslog after running irw twice:

So far I tried:
Blacklisting my unused imon modules ( in case they conflict, but it makes no
difference)
- Trying a lot lot of kernels; 3.5 and 3.8 for 12.04 LTS
(linux-image-generic-lts-quantal and raring) , 3.9, 3.10.
+ Trying a whole lot of kernels; 3.5 and 3.8 for 12.04 LTS
(linux-image-generic-lts-quantal and raring) , 3.9, 3.10.
- One kernel DID work, and that was linux-image-3.8.13-03081311-generic from
the ubuntu mainline ppa. However, this kernel caused system instability.
