Logicsupply lists some motherboards as "compatible", so I looked up the first Jetway one, and this is the Jetway pinout. This looks the same as my current Asus motherboard, in terms of pinout. Jetway happens to be using OC ("overcurrent") on their pin 10, but other motherboards will have a no connect on that pin. There are multiple standards out there, and as these things go, this is OK. (It would be better if Logicsupply actually put their own signal names on their own diagram, but nobody is perfect. Listing compatible motherboards is pretty lame.) VCC D- D+ GND OC VCC D- D+ GND (Pin 1 is on the lower left corner, a VCC pin) (Pin 9 is missing, and is used as a key.) There are like, a million connectors out there, and trying to match that particular four pin data one, would be pretty tough from this distance. In my business, connectors are so dangerous and deceiving, we don't design one in, until holding one in our hands. So each connector we use, we get samples. That is intended to prevent embarrassment when designing electronics and getting the connector wrong. Connectors are "simple", but at the same time, are a great way to have your reputation tarnished if you get something that simple, wrong :-) There is nothing like being in a rush to get some project done, the PCB comes back and the connector doesn't fit. Doh! You might be able to find a PCI USB2 card, with a Type A connector hole on an internal connector, which is another way to solve this problem. But that means, you're adding another USB chip to the computer. Paul
