V3 - PCB and schematics wrong for use of optional USB - FTDI chip
When the option for the USB - FTDI chip (FT2232HL) needs to be used, it will not work. There is a problem that appears when the optional components for this will be mounted.
See the attached image. Page 13 of the schematics shows that the line connected on the left of R248 is called USB_TMS (like the one connected to R243). The line to R248 should be USB_TDI.
