| 1 The patches contained in this directory need to be applied to the Linux kernel | |
| 2 ftdi_sio driver, specifically to ftdi_sio.c and ftdi_sio_ids.h source files. | |
| 3 This patch adds support for Falconia/FreeCalypso custom USB IDs with | |
| 4 appropriate quirks applied: | |
| 5 | |
| 6 * FreeCalypso buffered and unbuffered JTAG+UART adapters are recognized and | |
| 7 treated as such, creating a ttyUSBx device for Channel B, but not for | |
| 8 Channel A. | |
| 9 | |
| 10 * DUART28C USB ID is treated with the appropriate quirk, suppressing automatic | |
| 11 DTR & RTS assertion on ttyUSBx open for Channel B. | |
| 12 | |
| 13 The present patches have been made against Linux kernel version 4.4.14; | |
| 14 application to other kernel versions may require minor porting. |
