Weird State Machine issue

Thanks in advance for all suggestions... I have wrote a program to test a FTDI 2232H chip with a Cyclone 3 (EP3C25F324C6). The program is a simple STM, triggerd by a 60MHz clock of the FTD...

I've not looked over either your VHDL or C code but would only point out that the FT2232H may not be behaving exactly as advertised. In particular the Linux driver had some problems when I used the chip some years ago and the FIFO signals had some unexpected glitches on them. The Windows driver seemed to work fine.
