# MLAB Module XVC_FT220X for JTAG programming of Xilinx uses standard VendorID and DeviceID |
|
|

# of used FTDI chips. Unfortunately on latest Linux there is udev automaticaly loading |
|
|

# device driver ftdi_sio which creates ttyUSBxx device for any attached FTDI chip. |
|
|

# This driver prevents XVC program to comunicate with FTDI chip via FT2XX library. |

# It is necessary to disconnect (unbind) our FTDI device (identifyed by its name) from |
