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.
