I've already documented it at: http://linuxtv.org/wiki/index.php/Smart_Plus The device works if I try to use it inside a VirtualBox virtual machine running Windows. I believe the kernel driver that claims this device does not actually support it. The device is called "USB 2.0 ISDB-T Stick", model UTV926 (according to the manual), but I've also seen it mentioned as YS-926TV. USB vendor:product is 187f:0202. What can I do in order to make it work? -- Denilson Figueiredo de Sá Belo Horizonte - Brasil ^ permalink raw reply [flat|nested] 5+ messages in thread

The SMS1XXX_BOARD_HAUPPAUGE_WINDHAM board is likely close to this one. From drivers/media/dvb/siano/sms-cards.c: [SMS1XXX_BOARD_HAUPPAUGE_WINDHAM] = { .name = "Hauppauge WinTV MiniStick", .type = SMS_NOVA_B0, .fw[DEVICE_MODE_ISDBT_BDA] = "sms1xxx-hcw-55xxx-isdbt-02.fw", .fw[DEVICE_MODE_DVBT_BDA] = "sms1xxx-hcw-55xxx-dvbt-02.fw", .rc_codes = RC_MAP_HAUPPAUGE, .board_cfg.leds_power = 26, .board_cfg.led0 = 27, .board_cfg.led1 = 28, .board_cfg.ir = 9, .led_power = 26, .led_lo = 27, .led_hi = 28, }, I wrote the ISDB-T support for it, and it works properly. You'll likely need to add a new board entry there for it, and discover the GPIO pins linked to the leds and infrared (the numbers for .board_cfg and .led* on the above data structure). You can do it by either sniffing the USB board traffic or by opening the device and carefully examining the board tracks. After you have a patch adding support for it, please submit us the patch.

I've added two photos of the circuit here: http://linuxtv.org/wiki/index.php/Smart_Plus Considering there are these lines at sms-usb.c: { USB_DEVICE(0x187f, 0x0202), .driver_info = SMS1XXX_BOARD_SIANO_NICE }, I thought I didn't need to add a new board entry, just update the current one. Then I added a few lines, as shown below, but it seems the driver still tries to load "dvb_nova_12mhz_b0.inp" instead of "isdbt_nova_12mhz_b0.inp". If I rename (or symlink) the firmware file, the driver loads the firmware. After smsdvb module gets loaded, then there is a /dev/dvb/ entry for my device, but still the programs I tried (w_scan and vlc) don't find any channels. About the GPIO pins: even on Windows, the only LED from this device does not blink. So I don't care about LED feedback. Also, right now I'm not worried about IR remote, so I'm leaving that out. Anyway, I can supply some usb logs if they would help debugging this. --- sms-cards.c.orig 2012-01-20 00:42:47.000000000 -0200 +++ sms-cards.c 2012-01-20 01:05:11.000000000 -0200 @@ -92,6 +92,8 @@ /* 11 */ .name = "Siano Nice Digital Receiver", .type = SMS_NOVA_B0, + .fw[DEVICE_MODE_ISDBT_BDA] = "isdbt_nova_12mhz_b0.inp", + .rc_codes = RC_MAP_HAUPPAUGE, }, [SMS1XXX_BOARD_SIANO_VENICE] = { /* 12 */ @@ -299,6 +301,7 @@ case SMS1XXX_BOARD_HAUPPAUGE_WINDHAM: case SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD: case SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD_R2: + case SMS1XXX_BOARD_SIANO_NICE: request_module("smsdvb"); break; default: -- Denilson Figueiredo de Sá Belo Horizonte - Brasil ^ permalink raw reply [flat|nested] 5+ messages in thread

You may need to add it anyway, as the device may not be equal to Siano Nice reference board. > Then I added a few lines, as shown below, but it seems > the driver still tries to load "dvb_nova_12mhz_b0.inp" instead of > "isdbt_nova_12mhz_b0.inp". No. there's a parameter for the smsmdtv module to select the right standard: drivers/media/dvb/siano/smscoreapi.c:module_param(default_mode, int, 0644); You need to pass "default_mode=6" for ISDB-T to work. Just renaming the firmware won't work. Of course, the firmware name entry needs to be filled. Btw, adding both firmwares work, as the same device can likely be used in Europe with DVB-T. So, maybe we can add some parameter there to specify the default mode. Not sure if such change would be easy though. > > If I rename (or symlink) the firmware file, the driver loads the > firmware.

But, still, neither vlc nor w_scan can find any channels. I bet it requires deeper debugging and more knowledge than what I have now. -- Denilson Figueiredo de Sá Belo Horizonte - Brasil ^ permalink raw reply [flat|nested] 5+ messages in thread
