USB registers in SC589

Hello,

I'm working on a dedicated card with SC589. The USB port is connected to USB0 similar to the EZ-KIT. The USB is intended to work as a device. Unfortunately, the SW which works perfectly on the EZ-KIT does not work, and the controller seems to not recognizing a connection of the card to a PC.

I tried to view the registers, but the USB0 registers cannot be seen on the ARM (on which the SW runs).

What could be the reason for this?

Thanks, T.
