This steps have to be done in order to modify the Linux kernel module ftdi_sio.ko
so, that it accepts devices with the vendor/device IDs of the Atmel STK541 and/or the Dresden Elektronik Sensor Terminal Board and assigns them a serial device like /dev/ttyUSBxx
.
/usr/src/linux/drivers/usb/serial/
there are the files ftdi_sio.h
and ftdi_sio.c
, which needs to be modified.There are two patches available but most probably they will not work at a specific system, since in ftdi_sio.c
, the line numbers change rapidly by adding new devices from other vendors. So the patches most probably needs to be applied manually.
At first, the macros for the vendor and product ID of the boards have to be added in the file ftdi_sio.h:329
.
Next in the file ftdi_sio.c
the new Vendor/Device ID tuples needs to be added:
