>From the product page, it is a 1-seg device. So, it likely uses a sms1xxx
chip. 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.
Regards,
Mauro
