USB 1.1 and 2.0 mobo header

Don't think the physical connectors change from USB1.1 to 2.0, it's more to do with what they are plugged into ie the header on the mobo and what it supports.
 
that's strange. i remember in the past i have a usb header with less than 9 pin counts. i remember it because it doesn't fit my current mobo header so i had to buy a new one.

am thinking of buying a header for my other pc but need to confirm if all 9 pins header are USB 2.0 or they are specific to how it was made.
 
Same amount of pins, its the hardware that is different. I would check that the actualy configuration of the pins is correct, as there used to be different 'standards' a few years ago. USB only uses 4 pins, +5v, 0v, +signal, -signal. The ninth pin is for shielding.

im using a usb 2 bay mounted card reader and usb socket connected to a usb 1.1 header had to rearrange the pins so it worked though

some motherboards have different pin outs but the connectors should be the same?

i think older revisions used 2 seperate ground wires per header but not they use one?
 
Are you trying to attach one of these?

I have one from an old pc-chips 533mhz motherboard (usb 1.1) connected to a usb 2.0 mobo at the moment. It transfers data at usb 2.0 speeds. Only the 9th (dummy) pin was in the wrong place so I popped a hot needle through the blanked off part of the plastic connector to accomodate pin 9. Obviously usb pinouts weren't standardized back in the days of the pentium 2.
I'm such a cheapskate :D

yes that's exactly what i'm doing. I have purchased the USB header online and the seller said it's a USB 1.1 but told me it's a 9 pins. So I got really confused.

If it's got 2 ports on then regardless of USB1.1 or 2.0 it'll have 9 pins on it. All you need to make sure is that the pin outs of the header from the bracket match those with the header on your mobo.
