Greetings.. I have tried a DST VisionPlus 1020a dvb-s card today for the first time with a fresh copy of v4l (from today Jan. 16th). Upon loading the drivers I got the following message in dmesg: Linux video capture interface: v2.00 bttv: driver version 0.9.17 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:01:09.0, irq: 10, latency: 64, mmio: 0xdcfff000 bttv0: using: Twinhan DST + clones [card=113,insmod option] bttv0: gpio: en=00000000, out=00000000 in=00fefffe [init] bttv0: tuner absent bttv0: add subdevice "dvb0" bt878: AUDIO driver version 0.0.0 loaded bt878: Bt878 AUDIO function found (0).

After some searching I found a others experiencing the same problem and one of them posted the following: "The root cause of the problem seems to be that the DST card does not have PCI subsystem information configured: the bytes are just set to zero in the PCI configuration space. The driver linux/drivers/media/dvb/bt8xx/bt878.c checks for a set of subsystem IDs and only proceeds with the configuration if it finds one from the list." I then found the following patch that had been applied to the driver: ========== http://linuxtv.org/hg/v4l-dvb/rev/97edfa0f7c94 changeset 5513: 97edfa0f7c94 parent 5061: d5f262a7b702 child 6079: 358a897c1c19 manifest: 97edfa0f7c94 --- a/linux/drivers/media/dvb/bt8xx/bt878.c Sun Jan 07 20:12:22 2007 -0500 +++ b/linux/drivers/media/dvb/bt8xx/bt878.c Sat Apr 14 10:24:15 2007 -0300 @@ -397,9 +397,7 @@ static struct cards card_list[] __devini { 0xdb1118ac, BTTV_BOARD_DVICO_DVBT_LITE, "Ultraview DVB-T Lite" }, { 0xd50018ac, BTTV_BOARD_DVICO_FUSIONHDTV_5_LITE, "DViCO FusionHDTV 5 Lite" }, { 0x20007063, BTTV_BOARD_PC_HDTV, "pcHDTV HD-2000 TV" }, - { 0x00261822, BTTV_BOARD_TWINHAN_DST, "DNTV Live!

I have double-checked just to be sure and have confirmed the card only works with { 0, -1, NULL } included. Was the patch actually tested before it was accepted? I almost threw the card out because of this so I'm sure glad to discover the problem is in the driver! Hopefully it can be fixed before other think they have a dead card when they don't. Thanks. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
