Dont do that. Instead, copy contrib/99-openocd.rules to /etc/udev/rules.d/ to assign the required privileges to members of the "plugdev" group. > After executing the command I see this output with dmesg: > > [ 2446.706358] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now > disconnected from ttyUSB0 > [ 2446.706391] ftdi_sio 2-1.2:1.0: device disconnected > As long as ttyUSB0 was the first (JTAG) half of the FTDI chip and you still have a ttyUSB1 corresponding to the serial port of the flyswatter2, this is also expected. OpenOCD unloads any kernel drivers connected to the interface before claiming it. Although a setting in the adapter's EEPROM should prevent the kernel from attaching the serial driver to the first interface in the first place. Maybe that's not configured in the flyswatter. /Andreas
