Hello, I have been using various Hauppauge devices on Linux for years and I have a strange problem since I use a Hauppauge WinTV NOVA-T-500 (a dual-tuner DVB-T receiver on a PCI card which appears as 2 USB devices). I use the DVB devices from custom applications reading and analysing transport streams. From time to time, the application fails to start because the frontend0 device is no longer present. See that, frontend0 and net0 are no longer present under adapter0: $ ls -l /dev/dvb/* /dev/dvb/adapter0: total 0 crw-rw----+ 1 tlelegard video 212, 4 2007-09-17 14:41 demux0 crw-rw----+ 1 tlelegard video 212, 5 2007-09-17 14:41 dvr0 /dev/dvb/adapter1: total 0 crw-rw----+ 1 tlelegard video 212, 68 2007-09-17 14:41 demux0 crw-rw----+ 1 tlelegard video 212, 69 2007-09-17 14:41 dvr0 crw-rw----+ 1 tlelegard video 212, 67 2007-09-17 14:41 frontend0 crw-rw----+ 1 tlelegard video 212, 71 2007-09-17 14:41 net0 $ Note that the same application worked perfectly 5 minutes ago. I cannot say if the frontend device disappeared when the previous instance of the application terminated, when the new one started or some time between the two. It is not reproduceable at will (I have not yet determined what triggered the problem) but it reappears every few days. The only solution is to reboot the system. After reboot, the two adapters are back online. Here is a summary of the configuration: Distribution: Fedora 7 Kernel: 2.6.22.5-76.fc7 (i686) CPU: Intel Core 2 Duo Receiver: Hauppauge WinTV NOVA-T-500 Firmware file: dvb-usb-dib0700-01.fw Note that this system was previously running an x86_64 version of Fedora 7 and the problem was already there. A few weeks ago, I installed the i686 version of Fedora since I now use a Dektec modulator and the Dektec code is only provided as 32-bit binary (no source code and no 64-bit binary). So, the problem is seen on both 32-bit and 64-bit kernels. Is this a known problem? Any clue on how to fix that or at least bring the disappeared devices back online without rebooting the system? Thanks for any help, Best regards, -Thierry Lelégard _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
