The patches contained in this directory need to be applied to the Linux kernel ftdi_sio driver, specifically to ftdi_sio.c and ftdi_sio_ids.h source files. This patch adds support for Falconia/FreeCalypso custom USB IDs with appropriate quirks applied: * FreeCalypso buffered and unbuffered JTAG+UART adapters are recognized and treated as such, creating a ttyUSBx device for Channel B, but not for Channel A. * DUART28C USB ID is treated with the appropriate quirk, suppressing automatic DTR & RTS assertion on ttyUSBx open for Channel B. The present patches have been made against Linux kernel version 4.4.14; application to other kernel versions may require minor porting.
