I still haven't worked out if it's something I did yesterday (did mess around a bit) or something physical. Unfortunately, replacing the cable entails a certain amount of building work, but I should be able to devise a test to identify whether it's cable, USB header or power supply - already replaced a couple of years back when my first HDPVR died.<br /><br /><br />Yesterday I messed about a bit with a udev rule to set the audio encoding to AC3 (following wiki advice) through a script and also installed quite a few v4l2 dependencies to get the script working. After that, catting was not possible any more and even resulted in the cat process hanging so that even a kill -9 wouldn't remove it.<br /><br />Another think I notice is that the kernel is trying to load the PVR <span style="color: rgb(0, 0, 0); font-size: 12px; white-space: pre-wrap;">ir-kbd-i2c</span><br /> and zilog lirc modules and there is some firmware missing for those. I already tried setting the <pre style="color: rgb(0, 0, 0);">lirc_zilog tx_only=1 modprobe option, but apparently that parameter isn't suported any more. I'm going to try blacklisting all the related modules altogether, as I don't use any IR to or from the HDPVR.
Still not there, but learning ;)
