Pixelview bt878 卡无法识别

Pixelview bt878 卡无法识别

我在 Linux 上使用 Pixelview pv-bt878p+ rev.9d 时遇到了巨大的困难。我使用的是 Debian 内核,版本 3.2.0-1-686-pae #1 SMP。

当我加载该卡的 bttv 模块时,我得到以下信息:

[  683.700105] bttv: 0: unloading
[  690.772928] bttv: driver version 0.9.19 loaded
[  690.772941] bttv: using 8 buffers with 2080k (520 pages) each for capture
[  690.773719] bttv: Bt8xx card found (0)
[  690.773767] bttv: 0: Bt878 (rev 17) at 0000:00:0f.0, irq: 12, latency: 64, mmio: 0xcfdfe000
[  690.773817] bttv: 0: using:  *** UNKNOWN/GENERIC ***  [card=0,autodetected]
[  690.775504] tveeprom 0-0050: Huh, no eeprom present (err=-6)?
[  690.775516] bttv: 0: tuner type unset
[  690.777636] bttv: 0: registered device video0
[  690.779489] bttv: 0: registered device vbi0

我知道我可以向模块添加一些选项,所以我一直在尝试这样的操作:

modprobe bttv  card=72 tuner=38 radio=1 gpiomask=0x3F audiomux=33,32,35,35,40

modprobe bttv  card=70 tuner=38 radio=1 gpiomask=0x3F audiomux=33,32,35,35,40

我在互联网上找到了它,它解决了类似卡的问题。对我来说这是不成功的。

该卡的 lspci 给了我这个:

00:0f.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
        Flags: bus master, medium devsel, latency 64, IRQ 12
        Memory at cfdfe000 (32-bit, prefetchable) [size=4K]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2
        Kernel driver in use: bttv

00:0f.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

也许你们中的一些人知道我如何才能在 Linux 下开始使用这张卡?
