On my Intel DP55SB there is a Consumer Infra Red (CIR) header and a Nuvoton chip. The header has a CIR input and a LED output, and the LED should flash to indicate that a CIR command is successfully received. I have a receiver unit, with a IR-reciever chip and a LED indicator, connected to the header. I can boot either Win7 or Ubuntu, and the CIR input itself is functioning well in both environments. In Ubuntu, I am using LIRC devinput. However, I can see that when Win7 is used, the LED flashes as it should when I use the remote control, but when Ubuntu is used the LED is not flashing when I use the remote. Consequently, it must be a driver issue, and not hardware. I propose that the nuvoton_cir driver should be updated so that the LED indicator signal works as intended. BN
Hi all, I am willing to fix this issue. I am asking Nuvoton for w836x7hg's spec and waiting for their response now.
Johnny, Thanks for your effort, you now have the specs. However, I suspect the driver needed will be motherboard-specific, which means there will not be a general solution to this problem. I hope I am wrong. BN
