USB dvb-s2 adapter (Hauppauge 461e) signal problem

  • Hello, i've bought a Hauppauge 461e DVB-s2 usb stick to use in my LibreElec configuration. I've connected it to a T95z plus (s912), with "Adamg's [8.90.3] LibreELEC 9.0" on it. I had to install the CrazyCat driver before it recognized it. When i search for channels in tvheadend, it finds them all. But when i try to watch them it has too much errors in the streams to watch them. I can watch 2 channels with a lot of glitches, the other ones stay black with sometimes a piece of audio.

    I've tried to connect it to my laptop witch windows 10, then it works perfect with the same cable. Then i've tried a live usb libreelec on my laptop, also then it works correct. I then tried to use my laptop as tvheadend server and the T95z as client, also that works perfect. I've meassured the voltage output of the usb stick when connected to the t95z, it meassures 18v what seems to be good. I've also tried kzaq's version on the t95z, the same problem exist. When I connect other devices to the usb port like mass storage on the t95z they seem to work correct, so it seems it's not a problem of the usb port (or that is less sensitive). Does anyone knows a solution or other things i could try?

    For Hauppauge devices is preffered Huappauge driver addons. Try to switch to this addon.

    I've tried that, but than it won't get recognized. I'm not at home right know. When I'm home i will upload the log file with the Hauppauge driver add-on enabled

    I've now enabled the Hauppauge drivers add-on, now it's not recognized as dvb adapter in tv-headend. When i look at the log file i see it's recognized as a Pinnacle pctv 461e, Pinnacle is from Hauppauge, right? At least the store i bought it from, sell it is a Hauppauge and at the Hauppauge site i can find there is linux support for the 461e.

    Edit: After copy and overwrite CrazyCat's modules with the modules from Hauppauge and after that activate that addon and disable the Hauppauge addon is giving the same result, as not recognized in tvheadend.

    Shall this have something to do with this? "https://patchwork.linuxtv.org/patch/31598/"

    After that i removed both driver addons and installed the Hauppauge addon again, after a reboot i see that the folowing modules are loaded, but the adapter is still not showing up in tvheadend.

  • Could this thread be moved to bug reports? Because i now bought an rpi 3, and there i have the same problem. There is a video from Hauppauge on youtube where they letting see it works on a rpi 3, I use an 3,5 mha power adapter so that should not be the problem.

    However i didn't install the Hauppauge patch, it was recognised without it in tvheadend. I don't know if the patch was available for the rpi 3? And don't know if that could be the problem, but it didn't work anyway on the s912... i've installed osmc now, there it works correctly

  • Your issue is related to "PVR & DVB support". Ask CvH for help.

    You can try ls -l /dev/dvb/adapter*/ to see if is frontnend for dvb adapter is registered.

    Install from LE repository-> Program addons->DVB Tools and run w_scan] to see driver info.
