Looking at the reported endpoints, I'm guessing that you need to set CYGDAT_IO_USB_SLAVE_CLASS_TYPE to ACM to get the standard serial class driver setup. The generic option appears to set the class field to 'vendor specific' - presumably because omitting the interrupt endpoint renders it non-compliant with the spec. I suspect that there are plenty of 'vendor specific' USB products out there which are really just serial ports under the hood, and where the vendor drivers are only there to map them to a generic COM/TTY port.
