SX2's response to SET_INTERFACE request
How is SX2's response to SET_INTERFACE request different from its response to other EP0 requests ?

Returning a NAK from the CY7C68001 EZ-USB SX2 to the USB Host
The USB 2.0 specification says that when the USB host sends an IN token to a device, and if the device has no data to return to the host, it should respond with a NAK token. However, the CY7C68001 datasheet says there is no description and no register corresponding to generation of a NAK token. How does one return a NAK token using the SX2? Does the external master have to construct one?

SX2 device displayed as an 'Unknown device' on device manager.
While using the default SX2 descriptors as provided in section 12.0 of REV D version of the datasheet and the VID/PID reported in the device descriptor bound to the ezusb.sys driver (via the ezusbw2k.inf file). When the device is plugged in, it fails to enumerate and shows up as an "Unknown device" in the device manager. What could be the problem?

Slave FIFO Mode Synchronous Burst Read/Write with the CY7C68013 (FX2)
Does the FX2 device support synchronous burst read/write in slave FIFO mode? In the FX2 Technical Reference Manual, I am unable to find an I/O waveform of synchronous burst read/write with SLRD/SLWR asserted for the entire burst duration.

CY7C68001 EZ-USB SX2 INT# Pin Behavior for Multiple Interrupts.
The EZ-USB SX2 is capable of buffering multiple interrupts and INT# should be asserted if there is one or more pending interrupts. Must multiple interrupts be captured by an edge-triggered or level-triggered interrupt pin on the external master? For example, when there are two pending interrupts, reading the interrupt status byte clears the first interrupt. However, there is still one more pending interrupt, so the INT# line should be asserted again. INT# ___/ \__ (1) (2) INT# ______ (1) (2) Which waveform is correct?

External Processor Connection to the Host with the CY7C68001 - EZ-USB SX2.
How does a processor tell that the SX2 is connected to a host? When the processor gets connected, an ENUMOK interrupt gets sent using an EEPROM to load the descriptor. Is it safe to assume that if a BUSACTIVITY interrupt is seen that the processor is disconnected, and that if an ENUMOK interrupt is received it is connected? Or is there a better way to do this?
