Fiddling today with the FX2LP code I found that EP 6 (isochronous-in) which is used for UVC is double-buffered but it could also be quad-buffered. I configured the configuration bits to use quad-buffering and built the binary. Will be testing out difference in FPS performance. Here's a temporary link to download the binary.
The current situation with Cypress FX2LP needs us to significantly change our ways of integrating serial devices to HDMI2USB; the Cypress - FPGA route does not seem to work
It seems we will have to implement the serial expansion board as a standalone board using the PIC18F85J94 being planned to be used in production board.
It is also advisable to remove the control serial port currently implemented in Cypress FX2LP in order to free up endpoints for UVC A/B preview and HDMI audio input.
