Front USB Header Design
« on: May 14, 2013, 10:21:37 pm »
Hello everyone,
I am using GA-G41M Combo motherboard and need to design a custom USB 2.0 Bracket for my wonderful old chassis that doesn't have a Front Panel USB. So my question is, is the connection to the attached device from the Motherboard USB Headers is DIRECT or the USB Bracket offers some kind of filteration/regulation functions? I have a few USB Brackets in hand and they are all direct connections to the Motherboard headers, so any device connected to them will directly be connected to the Motherboard USB Headers. However, I've another USB Bracket from my compaq computer and it has some capacitors and SMD ICs built into the USB Bracket itself. I'm anxious as to not to risk damage to my motherboard by plugging something to the "unfiltered/unprotected" USB Bracket. I hope I'm able to clarify the question. If it is direct then I will be easily able to fabricate a custom USB Bracket PCB and fit it into my chassis.

I would use direct as i always have and had no problems that way.

The one that is the Brown PCB is Direct


The Green PCBs employ a capacitor and some SMDs between motherboard connections and USB Bracket. I'm wondering about the necessity of such design if the direct connection has no implications

your motherboard has its own protection  for the usb headers and has a Unique On/Off Charge delivers the best recharging capability to iPad, iPhone and iPod Touch. If you use the one from the old compaq you might defeat the purpose of the On/Off charge.

Also remember that Compaq was the low end of HP after they bought it out so it is likely that the stripped down motherboards they used didnt have protection for whatever you plugged into the usb so they had to have a self regulating board attached to the usb front panel. To Compaq whatever was cheapest was the way they went.

So if you dont plan on using the On/Off charge then it really doesnt matter except that i would almost expect the transfer speeds to be slower on the one with the capacitor/ pcb design.

Your third and last picture is pretty blurry so i cant read what is on it

Thanks for clarifying that :)
The Bottom picture (blurry one) is from a Thermaltake Chassis
That's what I was wondering about, so is it confirmed that my motherboard has its own protection for the USB Headers as well?
So I will go on with building the custom PCB Panel :)

All Onboard USB Headers doesn't have On/Off charge feature. Read here>> http://www.gigabyte.in/MicroSite/185/on-off-charge.htm
Apparently, my motherboard doesn't have these red and white colored USB Headers  :P
Can any one confirm if the onboard USB Headers are already over current protected and don't need any additional protection from the front USB Bracket?
