I built my first HTPC using the ASRock A75M-ITX board; so far, I'm very pleased with it. One area that's a little head-scratching, however, is with its CIR Header (which I want to enable in order to utilize my Rosewill RHRC-11002 remote). I've hooked up my front USB cable correctly and can get the IR dongle to work in the right USB port; the left port, however, doesn't seem to do anything. The manual states that it ought to act as a normal USB port. To test, I've been using a wired HP mouse; when I plug it in, the IR beam on the bottom glows (indicating it's receiving power?), but the mouse doesn't do anything.

I've triple checked the wiring and am certain that it's correctly placed. I'm hoping that someone out there has an answer for me.

For what it's worth, I'm using Windows 7 Home Premium as the OS.

Thanks!

If you're using the IR receiver that came with the Rosewill, you should plug it into a standard USB port, not the CIR header as far as I can guess. The CIR header is for use with just an IR receiver with no controller chips etc. Basically, if the USB IR receiver you have will work on any computer with a USB port, then don't use it on the CIR header port.

Thanks for the reply.

A bit more background - my primary reason for wanting to experiment with this is to have the remote be able to turn the PC on from a complete shutdown state. When I had the front USB ports wired to use both USB 2.0 headers (USB_67 and USB_89), I couldn't get the remote to turn the PC on; when I wired the ports to USB_89 and the CIR header, I was able to have the remote turn on the PC from shutdown (with the previously described side effect of not being able to use the left-hand USB port).

Another piece: I did configure my BIOS to allow USB keyboard/remote devices to wake the PC from S5 (this was done in both cases - where I'd wired both USB ports and where I'd wired USB_89 and CIR). I'm a bit green when it comes to how this actually works, so I'm not sure if this is correct.

I will rewire the ports to both USB_67 and USB_89 and see if I missed something. I'll report back.

Alrighty, I'm back and have some success.

I plugged the front USB cable back into the USB_67 header (anecdotally, I *think* I originally had it in USB_89) - no CIR. After one power cycle, I was able to turn on the PC using the remote and was able to use the other USB port as normal.

Thanks for the help! I appreciate it.
