I just setup a mini itx rig with the motherboard and a silverstone sg05 case. When I plug the USB front panel plug into the USB/CIR header as indicated in the manual, the fans spin up real loud and the board won't post. When I have it plugged into just the USB header it works. Any ideas? I'd really like to use the CIR since this will be a htpc.

Searching the net for the same problem brings up 2 relevant results. This thread and mine about the same thing on another forum.

Someone must have an answer to this?

Asrock could you read this and answer maybe?

Obviously still not addressed by anyone that could help. How can this be such an isolated issue that only 2 of us in the world have the problem? I wanna use the damn remote already!

If you want something done right do it yourself.

After more testing ive come to the conclusion its the front usb circuit board of the sg05 case that is causing the issue. I plugged in a spare usb header i had from an old pc and it boots up fine and im able to use the cir remote. So i de-pinned the sg05's cable and the spare i had and swapped connections. No dice. however with just 1 lot of the wires in the connector and plugged in the pc will boot.

Will silverstone send out a replacement board for the front panel?

ill contact them but thought id put this here for anyone else that may come across the issue.

The front usb circuit board is OK of the sg05 case. You can take any case same problem you have. If you read carefully manual: plug USB port for CIR directly into single USB header-4pin white color sits between two blue.
You need extra one single USB port with 4 pin plug, can use double USB port but one has to be left free. For the front USB + Audio board of the sg05 there is another header on the MB.

Now is my silly problem: anybody knows what for is black color header with 13 pins parallel to 24ATX ?

I guess you have no idea what you're talking about then. The idea of the front usb panel connecting the half of the usb header and the cir header is to allow one usb connection to function normally and one usb connection to allow the cir receiver to work correctly. Plugging in a seperate twin usb panel allows this to happen. The sg05's twin panel causes the system to fail to boot entirely. It is 100% the front panel in the sg05 causing the issue.

I contacted silverstone about it and they were no help at all. Ill contact them again to see if they actually feel like helping me out this time.

My friend, I tested about 3-4 different cases with front 2xUSB&audio panels & CIR header same problem. Connecting the half of the usb header and CIR header will allow ONLY ONE front usb to work which you can use it for remote control dongle. Second front usb connection must be left free. First before you boot be sure you plug the dongle to proper front usb connection wire color can help. I know it sounds stupid but everybody have a headache with this MB and cir header no matter what case they have. I add third USB connection, modified the front of the case and front usb/audio panel board now I have 2x working USB and one but ONLY for remote control dongle.

I have connected a 2xUSB panel to it from another case and have been able to use 1 usb for the cir receiver and the other as a normal usb connection.

This panel here and here is the one ive used with success. The silverstone panel is not working correctly. It seems ill have to mod the panel myself to accept the working one.

There you are, the 2xUSB panel on your pics is to place on the back of any case. This panel has no any electronic circuit board, there is no any interference between two USB input plugs, each one has own wires you connect directly to USB headers (half blue and CIR white) on MB. One of them will work with CIR header and only with remote receiver, second as normal USB port.
Mostly in all cases front 2xUSB/audio panel has own circuit boards, signals are mixed will work correctly only with one of double blue header as standard USB ports but not with this CIR receiver. That why you have two choices: modified yourself USB/audio panel electronic board on your Sugo case or add. third extra USB port. Hope I explain clearly English is not my home language.

Your english is fine i understand what you're trying to say. The circuit board isnt only "mixing signals" but is causing the pc to be unable to boot at all. It doesnt make sense that the board would cause problems anyway as the traces for each usb port are seperate from each other and the audio connections. Ill pull it apart again and see what i can come up with as it must be a short somewhere but it is very frustrating.

Thanks for your help though its good to at least talk it through with someone.

OK, before you do any modification to USB/audio board connect it just to one blue USB header on MB, leave white CIR header free. You should be able to boot without any problem and your two front USB ports will work as standard ports. In my case I added third front USB port and connected with single USB plug (5 pin, one is free) to CIR header, all problems solved. Same no problem after modification to the front panel board with 2 front USB ports but you need some electronic skills.
I think the problem is not with front USB/audio board as I tried 3-5 on another cases. If you look closely on MB blue USB header has 5&4 pins, according to the front USB/audio one double plug & wires & when you use only half of USB header and CIR 4 pins header (like in the manual) we have empty 5th pin on USB blue header. We should have all together 9 pins but with this type of connection we are getting only 8 pins. The traces on the board for each USB port are separate from each other but we still missing one pin. Looks like it is fault with MB design.

I had the same silverstone sg05 case, and I also found my system keep power on and off when connected front usb cable to cir & usb header as the manual described. I switch to another brand poower supply, it boots up fine,
however the usb mouse is not working, so I haven't install window yet.
It looks to me might not be the case front panel issue, it might be the power supply not strong enough, or this connection somehow caused short circuit.

Anyone have further experience?
