Help adding support for Hauppauge HVR-850 (latest version w/ USB ID 2040:b140)
Hi, The most recent version of the Hauppauge WinTV HVR-850 is currently not supported. The previous two hardware versions with USB ID 2040:651f and 2040:7240 are supported but the most recent version with USB ID 2040:b140 is not. I have identified the components in this new version (through a combination of reading the .inf file for the Windows driver and cracking the device open): Interface Bridge: CX23100 Tuner: LGDT3305 Demodulator: TDA18271HDC2 More details in my post on the discussion page for the device on the v4l-dvb wiki: http://linuxtv.org/wiki/index.php/Talk:Hauppauge_WinTV-HVR-850#Possibly_Valuable_Information I believe that all these components already have drivers available. I just don't have the experience to get them together in the cx231xx module. All previous HVR-850 and 950(Q) USB devices used the em28xx or au0828 bridge interface, so I don't have a template to work from in the cx231xx module. Discovering the gpio configuration is also beyond my experience. Any help? Or any existing development on this that I don't know about?

Re: Hauppauge 2250 - second tuner is only half working
I RMA'ed that tuner - awaiting a replacement. I found that adding and/or
removing all splitters made no difference (wasn't able to get a hold of a
proper attenuator - did try the splitter with a cap on one side method without
luck).
I did find shortly after a kernel upgrade, a few modprobes, a couple reboots,
some firmware file moves, and a dist-clean rebuilding the modules - that 2nd
tuner started working for the gap frequencies. I fired up mythtv and switched
over to watch the second tuner and it was working fine for about 30s, then the
system spontaneously rebooted. I played around a bit, but all subsequent
attempts to get the gap frequencies to work again failed (right back to same
problem as before - it won't get a lock, but first tuner was working fine). I
don't know if it was something with the state of my system just after a new
kernel was installed or maybe it was just coincidence (maybe the signal
attenuation was just right for a little bit there). Either way that spontaneous
reboot seemed like maybe the card / tuner hardware itself might be defective.
I still had a few days left to make good on my 30 day warranty so I figure I'd
give that a try. I'll let you know in a week or so if the new card is any
better.

I have the same problem as Seth. My system will tune RF channel 85 and
below will not tune RF channel 91 and above on the second tuner only.
First tuner works fine on all channels as does the PC HDTV 5500 also in
the system. My normal configuration is a 4-way splitter from the cable
into the house. One leg goes to a 2-way that feeds the two cards in the
system. With this configuration the normal result is:
Frontend /dev/dvb/adapter2/frontend0 tuned in 1 seconds.
Channel 80:Standard=ATSC, Modulation=QAM_256
SNR=0X0172, SIGNAL=0X0172
for channel 80 and:
Unable to set frontend /dev/dvb/adapter2/frontend0:frequency=66900,
modulation=QAM_256
for channel 103.
After reading Steven Toth's reply I tried adding 1 and then 2 2-way
splitters before the 2250 input. No joy. I also tried feeding the cable
directly into the 2250 with no splitters. Again - no joy.
Any other ideas?

Re: Hauppauge 2250 - second tuner is only half working
Well my card is out the door already. So it'll be a week or so till i can try again. I'll give it a pretty thorough run down when i get the new card, maybe I can dig up a repro. This is probably just a red herring, but FWIW I had never cold booted the machine (except monday morning when i yanked the card). I warm booted plenty, but i frequently would run full us-Cable scan's on both tuners. Some time last week when repo's pushed out 2.6.28-15, i had at least one warm boot in there where i had the modules/firmware missing. I reinstalled (dist-clean, make, make install), rebooted, and tried again and found it was working (well, for a little while until that spontaneous reboot). -Seth On 8/25/09 7:23 PM, Steven Toth wrote: I was able to repro the issue once however during patching the issue went away, never to return - regardless of whether the patch was active or not. I even ran a series of cold boots to try and repro the behavior but I cannot. I have seen the issue and I believe it exists, I just cannot get a reliable repro. If you can test tuner 1 on selected frequencies then test tuner 2 always against channel 103 (669MHz) and find a reliable repro case then I'll take another look.

Re: Hauppauge 2250 - second tuner is only half working
I'd really appreciate any help or guidance on this problem as i'm fully perplexed by it. Hey Seth, I ran the same tests on my cable system (channel 103) on 669Mhz and had no issue, and my snr's reported as (0x172 and 0x17c). One possibility is that you're overwhelming the frontend. Try adding a small mount of attenuation to the signal for test purposes. Hard to believe but this is where I'd start looking. -- Steven Toth - Kernel Labs http://www.kernellabs.com Thank you for reply! Hearing that the same frequency works on another card is pretty positive confirmation in my mind that this is a hardware/setup issue. I tried stopping by a local radio shack last night, but wouldn't you know they no longer carried simple attenuators. Looks like i'll be picking one up online (or maybe ill lookup a schematic online and try building a simple one). On a side note - Thank you very much for hacking on the saa7164 - other than this frequency glitch its been working great for me! -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
