Making it Work

I could not make it work. No device is created at /dev/dvb/*, even after the driver uploads the firmware. Maybe it is the wrong driver, or it does not work with this device.

I make a diffrent brand, same chipset work by **manually** loading the smsdvb kernel module (# modprobe smsdvb). Then the dvb device is configured successfully...(Vdragon) 02:40, 31 December 2012 (CET)


The Windows driver will install the firmware at C:\Windows\system32\drivers\isdbt_nova_12mhz_b0.inp. You can copy and use this file to your linux firmware folder (ex. /lib/firmware).

However, the driver from 2.6.38 and 3.1.8 kernels looks for the firmware named dvb_nova_12mhz_b0.inp, so you must either rename the firmware file, or create a symlink.


Both SMS_SIANO_MDTV and SMS_USB_DRV are required. They are already available in main Linux kernel.
