Hi,

I am retrofitting a crapard bell and I ran across the same USB panel today. I was going to rewire the header for my new motherboard, but then I noticed that the header had some different wiring.

I am not sure if you are using just the case or you still have the original motherboard. If you are replacing the motherboard, DO NOT connect this to the USB jumpers the way it is.

First thing to know: a lot of these proprietary computers use crazy "non standard" jumper headers.

I was about to attach the USB header when I noticed that the pins aren't in the usual layout:

5V D- D+ GND
5V D- D+ GND (2)


in fact it looks to be:

10V | blank | D+ | D- | blank
D+ | grnd | D- | grnd? | grnd?


The "grnd?" I can't really work out. The layout is bizarre. It looks like they are splitting the voltage. In the late 90's the big players were coming out with proprietary layouts so that they could make more money --- selling parts after warranty.

If you want this piece of crap and you are near The Netherlands, email me. You can have it.


Maybe your current one broke because you plugged it into a regular header?
