Thanks for your patch, applied!
Small remark about the older BM type chips: It will also set the
ftdi->index to "1" for the old chips.
According to my very ancient documentation, an index of zero (=default
interface) will be remapped to one (=SIOA). I verified it works by modifying
libftdi 0.x with "ftdi->index = 1" and run it on old hardware.
There's also code in ftdi_usb_open_dev() to set interface A,
maybe we can get rid of that?
Cheers,
Thomas
