You probably want to avoid running i2cdetect or any other tools that touch the i2c bus. We discovered that the IR receiver is very "intolerant". It disappears if you try to probe it in any way.

DViCO advises their windows user to unplug the power if the remote stops working suddenly :). It seems likely that a software reset may not be doable, otherwise I assume the DViCO software would have done that, but you never know. Note that you do not need to do the unplug power trick every time you power up the machine. The code is now safe enough that as long as no intentional i2c bus probing is done by the user, the ir receiver should work. The only time I had an issue was when I accidentally unplugged the ir receiver, then when I plugged it back in, the remote stopped working, so I had to do the power off trick. I have been using the remote since I submitted my patch about a year ago and that was the only time I had to cut power to my system to reset the IR. PS: See http://www.fusionhdtv.co.kr/ENG/Support/FAQRemote.aspx?act=RD&id=316&pg=0&CATID=13 for DViCO's support page which mentions the trick. -- Chaogui Zhang _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
