I think this is still the best option.

This does not really make sense for the intention of libftdi, which
is based on libusb (0.1 or 1.0) and libusb requires to detach
the kernel ftdi-sio driver. In that case, the use should not
use libftdi in the first place.

I think this is good to have. To me it is a bug of libusb,
a legacy from the original libusb-0.1 and carry on toe
libusb-1.0. I think your patch is good.
