| Post subject: | Setup impressions Knoppmyth and Mythdora |
Every now and again I try to setup a myth tv box just to see how it is progressing and lately I have been really surprised. I am a big fan of both knoppmyth and mythdora for making such an easy way to get your mythbox up and going. I still have a few minor issues but I am happy to say that yes most thing are working. I downloaded both from files.bigpond which made life easy! Here is my setup on my old hardware: System Setup System: AMD 2800 (2083MHz) runing on an Asus Motherboard (Piece of crap MB! Lan and Sound Dead) TV Card: DVICO FusionHDTV Dual DVB-T Remote: Fusion MCE Remote that came with the card. This remotes ir receiver is plugged into the card via what looks like a sound jack. The card was a little expensive at the time ($300) but i wanted two tuners so i could record while watching. Anyway i tried this setup using both distros: MythDora 3.2 http://g-ding.tv I tried this first as i very familiar with fedora having used it since version 3. Again I am still a linux newbie but can find my way around and I like using gnome. I had very similar problems in both knoppmyth and mythdora. Install was straight forward. After the initial setup i was greeted with a familiar desktop. Linux detected 1 of my 2 tuners and the remote didn't work. Time to poke around in linux. I headed over to /dev/ and found that yes dvb was there. so: cd /dev/dvb unfortunatly only /dev/dvb/adapter0 was there. So I had a look around on the forums to see what i was supposed to see. Looks like the second tuner is a usb one (this is why you have to plug the usb loop back into your card). Maybe it was some usb device... /dev/hiddev0 not there /dev/usb not there There was a /dev/bus/usb/001/003 that would disapear and reapear each time i removed the usb loop back thingy. A site suggested that i type in dmesg and look for anything interesting: Code: cx88[0]/0: found at 0000:00:0b.0, rev: 5, irq: 18, latency: 32, mmio: 0xbd000000 cx88[0]/0: registered device video0 [v4l2] cx88[0]/0: registered device vbi0 ACPI: PCI Interrupt 0000:00:0b.2[A] -> GSI 19 (level, low) -> IRQ 18 cx88[0]/2: found at 0000:00:0b.2, rev: 5, irq: 18, latency: 32, mmio: 0xbc000000 cx88[0]/2: cx2388x based dvb card DVB: registering new adapter (cx88[0]). DVB: registering frontend 0 (Zarlink MT352 DVB-T)... does the /2 mean that it can see the second reciever? Personally i think it is detecting the composite (aerial) and svideo in. dmesg should show it detecting the second reciever each time i plug it in right? So here goes. I unplug the usb cord and plaug it back in... and this appears at the bottom of my dmesg: Code: usb 1-2: USB disconnect, address 2
usb 1-2: new high speed USB device using ehci_hcd and address 3 usb 1-2: config 1 has an invalid descriptor of length 1, skipping remainder of the config usb 1-2: config 1 has 0 interfaces, different from the descriptor's value: 1 usb 1-2: configuration #1 chosen from 1 choice Oh crap.. this kernel or the modules don't know about my second tuner?!? This also doesn't bode well for my remote because under windows if i unplug my usb loopback the remote stops working. Checking the kernel version they are running 2.6.18... 2.6.20 is out but i wont be installing that and making a mess of things. At least i have 1 tuner working and I set up using the following: #mythtv-setup Capture Card Setup - Works This setup found my channels. Although the name of my card was incorrect. Card Type: DVB DTV capture card (v3.x) Dvb Card Number: 0 Frontend: Zarlink MT352 DVB-T Capure Card Setup - Mis-configurations These configs didn't work. Firstly trying to find the second tuner: Card Type: DVB DTV capture card (v3.x) Dvb Card Number: 1 Frontend: Could not open card number 1 --- Try different drivers, This detected the name of my card correctly but failed to find any channels. Card Type: pcHDTV DTV capture card (w/V4L drivers) video devcice: /dev/video0 (yes /dev/video0 exists) Name: DViCO FusionHDTV DVB-T Dual Dig [cx8800] Live TV Woohoo at least my channels were detected. And it found all of them! Up pops mythfrontend so i hit live tv. What a disapointment the tv was coming through choppy. Looks like about 2-3 fps (dunno how to check exactly what this is - any ideas?) Okies lets check to see if my video card was working properly. I have in an elcheapo ATI card and checked out how to install it at: http://news.softpedia.com/news/How-to-I ... 8740.shtml one of the lines to determine if it is working properly is: #glxinfo | grep direct direct rendering: Yes Cool it is working properly....but unfortunatly this is the last straw. I am not watching choppy tv. Time to see if knoppmyth is any better KnoppMyth R5E50 http://www.mysettopbox.tv/knoppmyth.html This is a smaller distro. It can fit onto 1CD. Not that it really matters cause i burn everything to dvd now anyway to get better read times. Installation was good except it looked like a few things failed in the setup. Like when it asked for an american zip code for weather or something. Again only 1 tuner was detected and the remote didnt work. same dmesg saying it dint know what was plugged in. /dev/dvb/adapter0 was the only 1 there. Same myth-setup. All the chanels were detected so there was only 1 thing left to do. check out live tv. Live TV OMG! The tv was coming through crystal clear at full frame rate! Well im going to have a play with this one now but there are still a few annoyances: #1 No browser except for lynx (yuck) and mythbrowser. I will work out how to get firefox on there hopefully. Or need to work out mythbrowser better. Doesnt work like I think it should. How do you type in an address... shouldn't the arrow keys allow you to edit the url? #2 my remote and second tuner still dont work. -- On a side note i disable the au_tv_grabber and use the following HOWTO to update my tv listings: SITE: http://tvguide.org.au HOWTO at http://minnie.tuhs.org/twiki/bi...w/TVGuide/MythTV -- My Questions are: 1. Is it possible for me to setup the second tuner? 2. Is it possible to get the remote working? |

After reading this thread http://mysettopbox.tv/phpBB2/viewtopic.php?t=12397 I found this: http://www.linuxtv.org/download/dvb/fir ... bird-01.fw but still gives the same usb error from dmesg: Code: usb 1-2: USB disconnect, address 2
usb 1-2: new high speed USB device using ehci_hcd and address 3 usb 1-2: config 1 has an invalid descriptor of length 1, skipping remainder of the config usb 1-2: config 1 has 0 interfaces, different from the descriptor's value: 1 usb 1-2: configuration #1 chosen from 1 choice Checked the remote was working in windows and it is. Still cant fire this baby up in knoppmyth?? |

So, does KnoppMyth win hands down over MythDora?!  I'd suggest checking linuxtv.org and lirc.org for details about the remote. If the remote is support under Lnux, you should be able to get it working w/ KnoppMyth. If you provide details on how you got it working, we'll made it work out the box.

when i ran lsmod I noticed that these last two drivers werent loaded.. is the usb driver supposed to load them when it is plugged in? moloth wrote: All devices below are fully supported by the LinuxTV driver. The following drivers are needed for these devices:
- lgdt330x.ko - mt352.ko - zl10353.ko - dvb-usb.ko - dvb-usb-cxusb.ko I loaded them manually using: Code: insmod /lib/modules/2.6.18-chw-13/kernel/drivers/media/dvb/dvb-usb/dvb-usb.ko
insmod /lib/modules/2.6.18-chw-13/kernel/drivers/media/dvb/dvb-usb/dvb-usb-cxusb.ko Is there anyway to make this permanent? Not that it seemed to make a difference when i plugged the usb back in. |

At the top of this page: http://linuxtv.org/wiki/index.php/DVB_U ... onHDTV_USB it says that i need to make sure that these modules are loaded: Quote: For all devices shown below you need to load (if not compiled into the kernel):
- i2c-core --already loaded - crc32 -- Not Loaded - firmware_class --already loaded - dvb-core.ko --already loaded - dvb-pll.ko --already loaded and maybe others too. If the loading fails for any particular module you'll get a "unkown symbol"-message. Then take a look at dmesg to find out, which symbols (functions) are missing. After you've found out which module was absent, please come back here and add it to the list/device-entry. I can find modules crc16 and libcrc32c but not crc32. perhaps I need a newer kernel? oh and instead of the insmod lines you can just use: Code: modprobe dvb_usb
modprobe dvb_usb_cxusb . |

Woohooo! Finally found my problem.. and it is so simple: edit /etc/modprobe.d/aliases change the line Code: alias char-major-81-* videodev
to alias char-major-81-* cx8800 /dev/dvb now shows adapter0 and adapter1 cat /dev/input/event2 now shows data when the remote is used only took me 4 days 
oh yea... you don't have to do those modprobe lines either! |

| Post subject: | Oh Smeg...then Success! |
Booted the thing up this morning and it was failing to work again... piece of *^%^. So again when i unplugged the usb and plugged it back in I had the dmesg: Code: usb 5-4: USB disconnect, address 2 usb 5-4: new high speed USB device using ehci_hcd and address 3 usb 5-4: config 1 has an invalid descriptor of length 1, skipping remainder of the config usb 5-4: config 1 has 0 interfaces, different from the descriptor's value: 1 usb 5-4: configuration #1 chosen from 1 choice So I reset my /etc/modprobe.d/aliases back to normal because this was now not the fix... it was more likely some fluke... but now I know it can detect the damn hardware. Looking at the error I noticed ehci_hcd which i think is the usb2.0 driver. So I did this: rmmod ehci_hcd then the dmesg said this: Code: ehci_hcd 0000:00:10.4: remove, state 1 usb usb5: USB disconnect, address 1 usb 5-4: USB disconnect, address 3 ehci_hcd 0000:00:10.4: USB bus 5 deregistered ACPI: PCI interrupt for device 0000:00:10.4 disabled usb 2-2: new full speed USB device using uhci_hcd and address 2 usb 2-2: configuration #1 chosen from 1 choice dvb-usb: found a 'DViCO FusionHDTV DVB-T Dual USB' in cold state, will try to load a firmware dvb-usb: downloading firmware from file 'dvb-usb-bluebird-01.fw' usbcore: registered new driver dvb_usb_cxusb usb 2-2: USB disconnect, address 2 dvb-usb: generic DVB-USB module successfully deinitialized and disconnected. usb 2-2: new full speed USB device using uhci_hcd and address 3 usb 2-2: configuration #1 chosen from 1 choice dvb-usb: found a 'DViCO FusionHDTV DVB-T Dual USB' in warm state. dvb-usb: This USB2.0 device cannot be run on a USB1.1 port. (it lacks a hardware PID filter) dvb-usb: DViCO FusionHDTV DVB-T Dual USB error while loading driver (-19) dvb_usb_cxusb: probe of 2-2:1.0 failed with error -22 OOh that looks promising! but it is still having errors... uhci_hcd looks like the usb1.1 driver?? and this is a usb2.0 device. Ok we will put the ehci_hcd driver back in. modprobe ehci_hcd then dmesg: Code: PCI: Enabling device 0000:00:10.4 (0010 -> 0012)
ACPI: PCI Interrupt 0000:00:10.4[C] -> GSI 21 (level, low) -> IRQ 19 ehci_hcd 0000:00:10.4: EHCI Host Controller ehci_hcd 0000:00:10.4: new USB bus registered, assigned bus number 5 ehci_hcd 0000:00:10.4: irq 19, io mem 0xbb000000 ehci_hcd 0000:00:10.4: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 usb usb5: configuration #1 chosen from 1 choice hub 5-0:1.0: USB hub found hub 5-0:1.0: 8 ports detected usb 5-4: new high speed USB device using ehci_hcd and address 2 usb 5-4: configuration #1 chosen from 1 choice dvb-usb: found a 'DViCO FusionHDTV DVB-T Dual USB' in warm state. dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.

Do the drivers have to be loaded in a certain order? and how do you do this? |
