Default Motherboard_USB_Microcontroller_Problem

Hi,


We have worked before with an EDV equiped with "p5q socket 775" asus motherboard, we have also our customized printed circuit based on HCS08 microcontrolleur. We used to make an usb communication between the motherboard and our customized board. (usb v2.0)

A several days ago, we have changed the old motherboard with a new one which is "p8h67 socket 1155" asus motherboard, with this new board we have found a problem of communication with our customized board by using the usb v2.0 protocol. In fact,sometimes the EDV didn't detect our customizd board.

So what could be the problem?

I'm waiting for you suggestions.

Regards,

I don't have a clue what "EDV" means so please provide some details.... don't assume everyone knows what your referring to, because we don't have one handy to check or examine.

And what does the sentence in BOLD of your post mean? I'm really not sure what you're asking for with your thread so break it down where we can understand what the hardware is and what the problem is.

In order to get USB 2.0 support you must have Service Pack 2 (or higher) installed. Without the SP install, the system will only be USB 1.1 compatible.
