Post subject: | Hauppauge wintv Nova-T stick |
I bought a Hauppauge WinTV Nova-T Stick but am having problem getting it working http://www.hauppauge.co.uk/pages/produc ... stick.html . I needed a USB device as I am building MythTV into a small shuttle PC that only has one PCI slot and I want to keep that free for a satellite card. I bought this particular item because I read a review of it somewhere where someone mentioned buying this USB device for their MythTV setup (and it just worked !) From what I understand in the “capture cards” section of the MythTV backend in amongst the other option like V4L, Firewire, etc, I should see a selection for “Digital Video Broadcast (DVB)” but that is not appearing I have tried two different Mythtv distros; Mythdora and Knoppmyth, and also tried in two separate machine I case it was incompatibility with my motherboard as I understand some VIA Chipsets can cause problems. But all combinations have shown the same basic problem My Linux knowledge is limited but doing “lusb” shows the stick is present I do have what seems to be the correct firmware file in /etc/firmware however I don’t have a /dev/dvb folder Have “grep”ed dmesg for references to “dvb” but found nothing. Any pointers on where to go from here would be gratefully received. Thanks Glen |

There appear to be three variants. see http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-Stick. All seem to now be supported by linuxtv, but some weren't when the cut of the dvb drivers was taken for release R5F27. I believe the next release will have updated dvb drivers and it may be that, if your stick is one of the versions that was not supported by linuxtv until recently, the newer drivers in the next release will help. You can identify the model by matching the output of lsusb with the identification table in the link above. If it is an older version, with any luck the USB-Stick works with the same modules and firmware as the Nova T 500 see http://www.knoppmythwiki.org/index.php?page=NovaT500 for instructions. Which firmware files have you tried? Even without the firmware files, I would have expected dmesg to have shown something when searched for dvb. The modules should be loaded and then log a failure to load the firmware. This can give a clue as to the name of the firmware file it is expecting and where to put it. Do you get any modules beginning dvb_usb listed if you display the loaded modules? Code: lsmod If not you could try and load them Code: #stop backend /etc/init.d/mythtv-backend stop modprobe --verbose --remove dvb-usb-dib0700 modprobe --verbose dvb-usb-dib0700 #restart backend /etc/init.d/mythtv-backend start You can then examine the tail of dmesg to see if anything happened Code: dmesg | tail -20 and also have a look in /dev/dvb to see if any devices created. Code: ls /dev/dvb
I would be interested to hear how you get on. babblefish |

when i did lsmod i didn't seeing any dvb modules loaded however i stopped the backend, ran the modprobe command you gave me and now when i do dmesg i'm seeing Code: dib0700: loaded with support for 2 different device-types usbcore: registered new interface driver dvb_usb_dib0700 and when i do lsmod i'm seeing a whole load of modules that weren't there before Code: Module Size Used by dvb_usb_dib0700 16520 0 dib7000m 17284 1 dvb_usb_dib0700 dib7000p 16132 1 dvb_usb_dib0700 dvb_usb 24332 1 dvb_usb_dib0700 dvb_core 73640 1 dvb_usb dvb_pll 17668 1 dvb_usb dib3000mc 15108 1 dvb_usb_dib0700 dibx000_common 7428 3 dib7000m,dib7000p,dib3000mc and when i unplug the stick and plug it back in dmesg reports Code: usb 5-4: new high speed USB device using ehci_hcd and address 3
usb 5-4: configuration #1 chosen from 1 choice Which is an improvement. though i'm having to invoke it manually. When i reboot i'm back to where i started. However i'm still not seeing a /dev/dvb directory and there's still no dvb option in the mythtv setup capture cards section The model i have appears to be a 1157 G (USB ID 2040:7070) and i have replaced the firmware file in /lib/firmware (not /etc/firmware as i said before) I've tried this one http://www.wi-bw.tfh-wildau.de/~pboettch/home/linux-dvb-firmware/dvb-usb-dib0700-1.10.fw and an even newer one http://www.wi-bw.tfh-wildau.de/~pboettch/home/linux-dvb-firmware/dvb-usb-dib0700-03-pre1.fw |
