我想尝试安装一个DVB-S2的USB设备到DM800上，但是DM800上没有Make文件不能执行驱动编译。哪位高手知道我该怎么做？ 
 
谁能指点一下？谢谢 
 
from now on all step are executed in /root/tbs, i.e. "cd /root/tbs" unless it's stated otherwise. 
 
I. install the QBOXS2 USB firmware file "dvb-usb-tbsqbox-id5928.fw" and CX24116 DVB-S2 Demodulator firmware file "dvb-fe-cx24116.fw" to /lib/firmware/: 
 
mv dvb-usb-tbsqbox-id5928.fw /lib/firmware/ 
shutdown -r now 
 
II.6 after reboot check that the newly installed driver is loaded correctly: 
 
dmesg | grep QBOXS2 
 
if everything is OK, the output from the above command should be similar to: 
 
dvb-usb: found a 'TBS QBOXS2 DVBS2 USB2.0' in cold state, will try to load a firmware 
dvb-usb: found a 'TBS QBOXS2 DVBS2 USB2.0' in warm state. 
DVB: registering new adapter (TBS QBOXS2 DVBS2 USB2.0) 
QBOX2: CX24116 attached. 
dvb-usb: TBS QBOXS2 DVBS2 USB2.0 successfully initialized and connected.
