Re: cx23885, new hardware revision found
I found there is a revision change - doesn't seem to affect the operation but needs a patch to be detected. See todays post.

Something else is wrong. I have both revisions of this board, and they display the same revision information as Hauppauge cx23885-based products: m...@codes:~$ dmesg | grep checkrevision [ 136.689267] cx23885_dev_checkrevision() Hardware revision = 0xb0 [ 136.914968] cx23885_dev_checkrevision() Hardware revision = 0xb0 [ 137.086548] cx23885_dev_checkrevision() Hardware revision = 0xb0 If it was a PCI card I would suggest moving it to another PCI slot, but I'm not sure that would help at all in the case of PCIe. DViCO has not updated their Windows driver since April of last year. I think that Michael Kutyna should confirm that the device works in windows before anybody proceeds to troubleshoot this any further -- it might just be a bad board / platform. -Mike Krufky -- 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

Re: cx23885, new hardware revision found
So does anybody have any ideas how I can attempt to proceed with this? I was thinking of looking in the code for the checkrevision function and commenting it out to see what happens but I suspect that I'll get the same lack of signal. It has been a few years since I have coded any C but I guess I can try.

cx23885, new hardware revision found
Hi, I just purchased a Dvico FusionHDTV7 Dual Express and intend on using it with MythTV. Unfortunately, the dvb-apps aren't working with it just yet and I think I've narrowed down why. I've used mercurial to get the latest v4l-dvb source, compiled and installed the modules. I downloaded the firmware from Steven Toth's website, extracted and installed it. This all seems to run fine. Running scan against the us-ATSC-center-frequencies file returns no channels and running femon -a 0 returns the following output: status S | signal | snr | ber | unc | After examining dmesg output, I noticed the following bit: cx23885_dev_checkrevision() New hardware revision found 0x0 cx23885_dev_checkrevision() Hardware revision unknown 0x0 cx23885[0]/0: found at :02:00.0, rev: 4, irq: 17, latency: 0, mmio: 0xfd80 cx23885 :02:00.0: setting latency timer to 64 I'm pretty sure that is the problem but I don't know how to fix it.
