Hello,

I have a question about how to properly use Ftdi::List and Ftdi::Context. I
want to make sure that I won't leak memory or double-delete something.

Does deleting an Ftdi::List delete all the Ftdi::Context objects that came
from it, including open ones? So does that mean that contexts individually
should not be deleted? Also should contexts be closed before the list is
deleted?

Also, if I list devices, and I see a list of devices A, B, and C, and I
open only B, does that Ftdi::List existing in memory prevent another thread
from listing and opening A or C?

Best,
Owen
