Renumeration with a new EEPROM VID/PID
My firmware changes the VID/PID in the I2C EEPROM used to identify my device when it is initially connected. Once the VID/PID is changed, the firmware performs a renumeration. But the new VID/PID is not picked up and the original firmware loader is used. If I unplug the device and reconnect it, the new VID/PID is used and my new firmware loader is used. How can I get the EZUSB to refresh its VID/PID from the EEPROM when it renumerates?

GAL code file does not match CY3684 Schematic
The EZ-USB Development Kit Manual - Getting Started pdf on page 19 contains the GAL code. Under the Input section CLKOUT is assigned pin 2. The schematic shows nRD going to pin 2. Which is correct?

Address Valid Time When Using AUTOPTR1/2 for External Data Memory Access
When the FX2/FX2LP 8051 runs the code above, the address valid time is only for 2 CLK cycles: different from what is stated on page 39 of the datasheet. The MOVX @DPTR, A and MOVX A, @DPTR with DPTR pointing to one of the autopointers have a data cycle with the target address only valid for 2 FX2 Clocks.
The external 8051 bus does not agree with the timing diagram outlined in sections 9.3 and 9.4 of the datasheet.

'NULL' identifier .
Four of the files in the EZ-USB & FX2 libraries (get_dscr.c get_infc.c get_strd.c get_cnfg.c) compile with the same error. The following is the error message for the get_cnfg.c source file compilation:
*** ERROR C202 IN LINE 22 OF GET_CNFG.C: 'NULL': undefined identifier
C51 COMPILATION COMPLETE. 0 WARNING(S), 1 ERROR(S)
It seems that the NULL macro that these functions use as a return value, is not defined. What needs to be done to get these modules to compile in order to rebuild the library?
