Hello, I've been using a Hauppauge Nova T 500 for a while using Ubtuntu Hardy with an occasional "mt2060 I2C read failed" error, but it's been tolerable. After upgrading to Intrepid Ibex it's now failing the instant the second tuner kicks in. A reboot doesn't fix the problem. I have to shutdown and start from cold to clear the error. Any help would be greatly appreciated. I've read the recent threads on the subject at http://www.linuxtv.org/pipermail/linux-dvb/2008-June/026715.html http://www.linuxtv.org/pipermail/linux-dvb/2008-February/023738.html and many older ones. I've installed the lasted drivers and firmware from http://linuxtv.org/hg/v4l-dvb I've add the following to /etc/modprobe.d/options options dvb-usb-dib0700 force_lna_activation=1 options dvb_usb disable_rc_polling=1 options usbcore autosuspend=-1 and follows the instructions at http://www.blackberryforums.com/linux-users-corner/97661-enable-disable-config_usb_suspend-s-autosuspend-mode.html to rebuild the initrd for my kernel. I've tried the dvb-usb-dib0700-1.20.fw and dvb-usb-dib0700-1.10.fw firmware. I've edited my mythtv setting in accordance with the instructions at http://www.youplala.net/linux/home-theater-pc#toc-not-losing-one-of-the-nova-t-500s-tuners If I "echo on > /sys/usb_device/.../device/power/level" to all the usb devices set to auto, then I don't seem to get the mt2060 errors. (I waited 10 minutes and it never turned up.) However I still get [ 1661.529152] dvb-usb: error while enabling fifo. within seconds of the second tuner starting to record, and Mythtv then locks up. (The current driver fixes all the problems I had with uvcvideo and the USB microphone on my Logitech QuickCam Pro 9000, so I really want to upgrade.) I would appreciate any clue on what to try next. Regards and Best Wishes, Robert Watkins P.S. The firmware often fails to load first time.
