As the exact C structure:
class FtdiContext(Structure):
"""Libftdi context, as a Python ctypes structure"""
_fields_ = [# USB specific
('usb_dev', POINTER(UsbDevice)),
('usb_read_timeout', c_int),
('usb_write_timeout', c_int),
# FTDI specific
('type', c_int),
('baudrate', c_int),
('bitbang_enabled', c_ubyte),
('readbuffer', POINTER(c_ubyte)),
('readbuffer_offset', c_uint),
('readbuffer_remaining', c_uint),
('readbuffer_chunksize', c_uint),
('writebuffer_chunksize', c_uint),
# FTDI FT2232C
('interface', c_int),
('index', c_int),
# Endpoints
('in_ep', c_int),
('out_ep', c_int),
('bitbang_mode', c_ubyte),
('eeprom_size', c_int),
('error_str', POINTER(c_char)),
('async_usb_buffer', POINTER(c_char)),
('async_usb_buffer_size', c_uint)]

Not really difficult per se.
It's just annoying to declare the USB structures (I've done it to
perform some debug tasks), but it's quite easy to write.
