uirt2_raw: checksum error

[Jared Harvey]

This appears to be the same issue as noted at this link. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/177166

I have a new usbuirt that I want to use as an IR transmitter/receiver for mythbuntu 11.04. From a fresh boot, I do the following.

$ sudo /etc/init.d/lirc start
 * Starting remote control daemon(s) : LIRC R3 start-stop-daemon --start --quiet --oknodo --exec /usr/sbin/lircd -- --output=/var/run/lirc/lircd --driver=usb_uirt_raw --device=/dev/ttyUSB0 -l --listen

I modified the initscript to echo the start stop daemon commands. That is where the R3 and R4 lines noted above came from. The init script claims it launched OK, but notes that there was a problem. Before running the script, there was no file under /var/run/lircd so I don't know why it has a problem with getting the socket. Then irw failed to produce anything when I pushed buttons on the remote, while I watch the LED on the uirt blink. I then ran mode2, which verifies that LIRC is connected to the uirt device via USB and it's passing bits to LIRC. My current understanding of problem is that the driver for ttyUSB0 has changed and it doesn't communicate correctly with LIRC. The last thing I did was to verify that my config files loaded correctly, with irsend LIST. The haupauge note is the remote, the dish's are for transmitting to the dish receiver. Thinking that perhaps the config files might be broken, I tried making my own with once seemed to work, but typically fails on that error message. I once got KEY_0 to come through as 00, KEY_1 as 01. Which worked, and was much different than 0x0000000000001001 noted in lircd.conf.hauppauge.

I believe the key issue is that I need an updated config file, however I can't create it with irrecord, as it appears that program fails because of the checksum complaint.

Here's my hardware.conf file.

My /etc/lirc/lirc.conf has several comments, and one line

include "/usr/share/lirc/extras/transmitters/dish/general.conf"

According to synaptic
lirc (0.8.7-0ubuntu4.1)
mythbuntu-control-centre (0.63-0ubuntu1)

some syslog notes that might be of interest include

Also I expect to be using the driver usb_uirt_raw, not uirt2_raw which is a valid driver, just not the expected driver.

I'm new to this bug reporting, so feel free to contact me at <email address hidden> for more information if there is something I can do to help with resolving this problem.

[Jared Harvey (o-launchpad-jaredharvey-com)]

I got receive working. It appears that something crashes or doesn't fully clear itself out when with lircd stop is called. With reboots to help keep things cleaner, I got irrecord to work such that I could create my own config file. I then compared it to the provided config file and found my newly generated config file had almost the same items as in the original config file. However remote Haupauge is listed twice. The first on the list was not the setting I needed. It appears the remote name found higher in the lircd.conf file trumps any that are posted lower down. I copied /usr/share/lirc/remotes/hauppauge/lircd.conf.hauppauge to /usr/share/lirc/remotes/hauppauge/lircd.conf.hauppauge.mod then deleted the extra remotes that I don't need, such that only the remote definition was left is in this file. I then modified /etc/lirc/lircd.conf to use the .mod file. So now receive works. However transmit does not work. Also I run a risk of breaking these changes if they don't get included in "Mythbuntu Control Centre" So even though I have it working on my machine, I consider it a bug, as the graphical config tools would break it.

[Jared Harvey (o-launchpad-jaredharvey-com)]

I seem to have this physically working, but mythbuntu control centre's IR section will cause this to fail if I use it. So I consider it a bug. I posted my findings at this wiki page.

https://help.ubuntu.com/community/Lirc_USB-UIRT#Specific to Mythbuntu 11.04

If there is anything I can offer to help get mythbuntu control centre to allow this to work out of the box, let me know and I'll see what I can to do help.

Jared Harvey, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
