USB UIRT learn - transmit problem
« on: April 20, 2009, 11:17:22 pm »
Hi,

I have a standard usb-uirt. I want to control my cable box. Through the web config I learn codes for 0-9 and <enter>. When I "test" the codes however, nothing happens at the side of the cable box. The LED on the usb-uirt flashes once, quickly. The actual remote, from the same spot as the UIRT, controls the STB without a problem.

If I relearn the codes, I get different results (i.e. the string of 4-digit codes) now and then. Is that normal? Relearning does not help.

Does anyone have a suggestion here? I figured since the LED flashes, the UIRT is reached by the dcerouter, but something is wrong somewhere!

Thanks,

Mark

Domodude,

I assume you are using i386? And you are trying the USB UIRT without an IR extension dongle?

building on what posde said - in 0710, the USBUIRT has a bug on i386 machines that require an external dongle for it to work. However, if you look around the wiki, you will find that somebody did put up instructions on how to fix that bug (and even included a new binary to make it easier)

Regarding the IR learning - sometimes the IR learning will "miss" the attempt to learn a code and return a 4 digit code as you described. Just relearn the code again until it looks normal. Also, having fresh batteries and being consistent in you remote positioning during learning helps a lot.

I am sure that this will solve it, thanks Seth! Don't know how I missed that...

Hello,

  I'm having a similar issue, the learning works correctly (at least it appears to work correctly), though when I test out the transmit it does not. I have utilized the wiki instructions (thanks Seth!) and actually updated the wiki with some updated info on the git command. After playing with and attaching a an extension on the back I still have no luck with the transmission. The plugged-in extension does not blink when i send a test through, though the UIRT dongle itself does. Would anyone have any ideas on further troubleshooting this?

Here are the steps i've taken up to this point:
1. Rebuilt diskless MD image with base/default 710
2. Attached extension to the back
3. Followed Seth's article and also tried to use the binary he created - upon doing this the kernel recognized the dongle and pulled it into mce, mce autoconfigured it the way i would expect and can learn just fine via the web admin tool.

P.S. The driver looks very different in 810, has anyone tested this in 810 successfully?

Thank you!

Ryan
