Mythbackend and hauppage USB tuner problems

I'm coming from using ubuntu for the last year and I've switched over to arch around a month ago. Everything on my server is running nicely and I've learnt more about Linux in the last few weeks than I did in a year of ubuntu, but I've got one last little problem I can't wrap my head around.
Please bear with me because I'm no where near my pc ( and won't be untill the weekend, but I've got remote ssh access to it if needs be )
with ubuntu I've been using a hauppage wintv nova T500 pci and a wintv USB stick. The pci card mounts itself as 2 USB tuners. I've loaded the firmware for the tuners (they both use the same firmware) and they show up when I check lsusb and dmesg.
I've tried mythtv from the repo and mythtv .22 built from the aur, both are giving me the same problem.

Mythbackend is loaded as a daemon in my rc.conf file and it loads fine but then errors out as it can't find any tuners.  the only way I can get myth to work is to unplug the USB tuner and pci card, remove mythbackend from my daemons and when I start the pc up plug the USB tuner in after I get to the command prompt then manually start mythbackend. This way it works fine everytime but I can't use the pci tuner as I don't fancy plugging that in while the pc's on

any help would be Appreciated as it's driving me nuts, I can grab any logfiles anyones after once I finish work (posting this from my phone at work)

Forgot to say that myth loaded fine using these tuners and the exact same hardware under ubuntu

Re: Mythbackend and hauppage USB tuner problems

What do you get when you run the following?

dmesg | grep dvb

thats just the usb tuner plugged in, i took the pci one out before i left for the week.
to me it looks as if its registered properly and everythings fired in. But like i said im new to Arch and i was kinda used to just plugging stuff into ubunutu and it automagically working

Re: Mythbackend and hauppage USB tuner problems

Yep - looks like that is initialised properly. I have a Nova-TD-500 that uses the same firmware and that's almost identical to what I get (although I don't get the 'Modules linked in...' line)

See If you get any messages when you run 'sudo mythtv-setup' from a terminal and have a look at the end of /var/log/mythbackend.log for clues

Re: Mythbackend and hauppage USB tuner problems

ive just rebooted the pc remotely with the usb tuner plugged in,  dmesg | grep dvb is giving me the same output but if i use  dmesg | grep DiB (DiB0070 is the firmware) i get pages full of:
DiB0070 I2C write failed
DiB0070 I2C read failed
DiB0070 I2C write failed
DiB0070 I2C read failed
DiB0070 I2C write failed
DiB0070 I2C read failed
DiB0070 I2C write failed
DiB0070 I2C write failed
DiB0070 I2C write failed
DiB0070 I2C write failed

and im not at a loss what to do next, i suspect if i pull the stick out and plug it back in again it will work fine but i can physically get to the machine.

Re: Mythbackend and hauppage USB tuner problems

I wonder if  something is running out of order. Try moving the MythTV daemon before HAL (if you're using it).

Re: Mythbackend and hauppage USB tuner problems

Sounds to me like the tuner is initializing properly, but myth doesn't know about it. It will throw that error if the database isn't up.

See if mysql is running (pgrep -l my).

Re: Mythbackend and hauppage USB tuner problems

thanks for everyones help. ive shifted mysqld and mythbackend in my daemons line to near the front, just before hal.
mysql wasnt running because of a noob mistake by me (i had mysql in the line not mysqld).

im back physically infront of the pc tomorrow so i can see if it all worked properly, fingers crossed.
