It is mostly working now – I can tune live TV using it and recordings fire off a channel change. I’ve got a problem with my channel change script when starting a recording (which doesn’t happen with live TV) but I should be able to figure that out on my own. But I also see that the HD-PVR sometimes doesn’t stop recording. The show it tried to record (but recorded a different program instead due to the aforementioned script issue) lasted a half hour and MythTV seems to have correctly stopped recording at the half hour mark even though the HD-PVR didn’t get the notification to stop recording. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>To try and debug it, I thought about looking into a script to reload the hdpvr module. Seemed simple enough and there are script examples out there. But when I try typing the following in the command line: <o:p></o:p></p><p class=MsoNormal> sudo modprobe -r -v hdpvr<o:p></o:p></p><p class=MsoNormal>the command just hangs there indefinitely showing:<o:p></o:p></p><p class=MsoNormal> rmmod hdpvr<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> I can kill the sudo process that kicked off the modprobe but I can’t kill the modprobe process. The only way I have found to clear the problem is a reboot and even then, during shutdown, the process won’t die and hangs the computer on the waiting for processes to end step requiring me to push and hold the power button. Nasty. Clearly something is very wrong somewhere. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This is what I see in dmesg before trying the modprobe –r:<o:p></o:p></p><p class=MsoNormal> [ 15.456135] hdpvr 1-3:1.0: firmware version 0x1e dated Mar 7 2012 08:25:15<o:p></o:p></p><p class=MsoNormal> [ 15.966780] hdpvr 1-3:1.0: device now attached to video0<o:p></o:p></p><p class=MsoNormal> [ 15.966841] usbcore: registered new interface driver hdpvr<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>And this is what I see from dmesg after the modprobe –r starts (and then hangs):<o:p></o:p></p><p class=MsoNormal> [ 15.456135] hdpvr 1-3:1.0: firmware version 0x1e dated Mar 7 2012 08:25:15<o:p></o:p></p><p class=MsoNormal> [ 15.966780] hdpvr 1-3:1.0: device now attached to video0<o:p></o:p></p><p class=MsoNormal> [ 15.966841] usbcore: registered new interface driver hdpvr<o:p></o:p></p><p class=MsoNormal> [ 846.134280] usbcore: deregistering interface driver hdpvr<o:p></o:p></p><p class=MsoNormal> [ 846.134308] hdpvr 1-3:1.0: device video0 disconnected<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If I don’t plug in the USB connection to the HD-PVR when I boot up, the hdpvr module doesn’t get loaded, of course. So I can modprobe hdpvr and it loads fine. Then I can modprobe –r no problem. The inability to remove the hdpvr module could be related to the way the device keeps recording sometimes. So I’m hopeful that fixing one will fix the other. But I’m out of ideas about what to check or what could be the source of the problem. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am running Mythbuntu so my setup for the HD-PVR was pretty easy. Mostly just plugged it in and set it up in the Backend setup. A few extra steps to enable the IR flashing. And I did start with updating the firmware to the latest using a Windows computer. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I have checked my BIOS settings for USB settings. I don’t have much in there for options (6 year-old ASUS BYO) and what is there seems to things set appropriately, at least as far I can tell. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anybody have suggestions on where to look to chase down a problem like this (or these, as the case may be)? Thanks!! <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ken. <o:p></o:p></p></div></body></html>
