    Unhappy CIR-Problem on A75M-ITX

    Hello,

    i am having a very strange problem installing a CIR-receiver on my A75M-ITX.

    I installed the CIR (its an internal one originally for Intel-Boards, but i know it works on Asrock-Boards after changing some Pins on the Cable)
    After the setup of Win7 32bit, i installed all drivers, the CIR-driver last. After the install i rebooted the system as requested by the setup-program.
    In the device-manager no CIR-related devices show up and i couldn´t controll anything with my remote...

    First i checked if the CIR was installed proberly, all cables where in place. The BIOS altough lacked all Options regarding a CIR. I started the PC anyway and deinstalled the CIR-driver, suddenly the device-manager showd a "Novoton something CIR" and a "Microsfto eHome-Receiver". Also the remote was working, i was even able to put the PC to sleep and wake it up again.

    After another reboot the 2 devices where again gone from the device-manager and the remote was no longer working. I checked the BIOS again and there the CIR-related options where back. Back in Windows, i tried reinstalling the driver, but got the error "No CIR present".

    Long story short, after hours of testing later i got the following situation:
    1. When i remove the power-cord for a few seconds the BIOS "forgets" that there is a CIR installed (no related options in the BIOS). As long as no CIR is present in the BIOS, Windows device-manager shows a Novoton something CIR" and a "Microsfto eHome-Receiver" and the remote is working.
    2. After 1-X reboots or 1-X wakeups from sleep the devices are suddenly gone. Checking the BIOS shows that the CIR-options are back. Installing the drivers brings the above-mentioned error.
    3. I remove the power-cors again, goto 1

    Any Ideas? I am really out of ideas...

    best regards
    Hadan

    I assume that when you pinned which wire from your Intel CIR to the applicable CIR header that you followed the wiring schema from your manual. Also that you connected your front USB header (where the USB dongle for the CIR Receiver gets plugged into) to the USB 6_7 header...The fact that it's intermittent in that it works sometimes, yet does not other times esp when the power cord to your rig is unplugged. Suggests that maybe your CMOS battery is on the edge and needs replacing ie: "BIOS forgets". Or you have one or more of the wires in the CIR header is just loose enough that any motion to your rig even something as simple as unplugging it disturbs the fragile connection. Double-Check that all of your wires to the CIR header are seated perhaps with a magnifying glass...
    Keep us in the loop on your findings

    The guy i bought the receiver from did the re-wiring, but as far as i have checked the pins are in the right order. I will double-check again.

    The receiver is internal. Its conncted to the CIR-Port and one Pin is placed on USB6 for power. Here is a picture:

    I will try that.

    I will check that too.

    Whats really bothering me is the fact that if the BIOS recognizes the CIR Windows does not and vice versa...

    Thanks for your help, i´ll keep you informed.
