Hi,

I have strange problem when I use CY7C67300 in co-processor mode.

It failed to detect when a USB device is plugged in. The Port Connect
Change Interrupt Flag in Host Status Register is always 0.

Do you have any idea of this problem?

Thank you very much!

Wendy

It seems that the cypress devices on the Xilinx ML40x / ML50x boards come with an EEPROM with firmware in them, and some variants of the chip doesn't work very well without it. I don't have access to any of those boards and I don't know the difference between that firmware and what's in the ROM unfortunately. -- Bye, Peter Korsgaard
