I'm installing MythTV on a new Ubunto Feisty Fawn system. The last
obstacle to actually using it for watching TV is getting the remote
control to work.
I'm using a StreamZap USB remote. I've confirmed that the device is
registering itself. The output of dmesg | grep usb includes:
[ 36.440370] drivers/usb/serial/pl2303.c: Prolific PL2303 USB to
serial adaptor driver
[ 63.037702] lirc_mceusb2: no version for "lirc_get_pdata" found:
kernel tainted.
[ 63.042053] lirc_mceusb2: Philips eHome USB IR Transciever and
Microsoft MCE 2005 Remote Control driver for LIRC $Revision: 1.25 $
[ 63.042057] lirc_mceusb2: Daniel Melander <lirc at rajidae.se>, Martin
Blatter <martin_a_blatter at yahoo.com>
[ 63.046141] usbcore: registered new interface driver lirc_mceusb2
So far so good. I confirm that the lirc_mceusb2 module is loaded:
root at myth:~# lsmod | grep lirc
lirc_mceusb2 16004 0
lirc_dev 18504 1 lirc_mceusb2
usbcore 154416 7
lirc_mceusb2,pl2303,usbhid,usbserial,ehci_hcd,ohci_hcd
I've followed the lirc installation instructions at
<https://help.ubuntu.com/community/Install_Lirc_Feisty>. All goes
smoothly until it's time to test lirc. irw returns immediately to the
command prompt, and lircd fails after logging this:
Sep 8 23:03:27 myth lircd-0.8.2-CVS[5097]: accepted new client on
/dev/lircd
Sep 8 23:03:27 myth lircd-0.8.2-CVS[5097]: could not get file
information for /dev/lirc

or directory
Sep 8 23:03:27 myth lircd-0.8.2-CVS[5097]: caught signal
And sure enough there's no device file.
root at myth:/var/log# ls -l /dev/lirc*
srw-rw-rw- 1 root root 0 2007-09-08 22:51 /dev/lircd
I've spent most of today looking at mailing list archives and web pages,
and really haven't seen a good solution to this problem.
I'm running kernel 2.6.20-16-generic and lircd 0.8.2-CVS. When I run
modinfo lirc_mceusb2 I get:

Seems to match the kernel version, so I'm out of ideas. I hope one of
you can point me toward the answer, or at least toward the right question.
This is my first Ubuntu system, so I've got about one day of experience
with the package management tools.
