Revert "Don't measure CC lines twice"
This reverts commit 248085cfe30a7dcf2ae819173604a0ae869c5612.
It appears that my M1 mini running some ancient firmware insist
on requiring the double checking, and displays the following
syndrome:
P0: S: DISCONNECTED
P0: Poll: cc1=2 cc2=0
P0: Connected: cc1=1 cc2=2
P0: Polarity: CC2 (flipped)
The first read of the CC lines reports something that is completely
wrong, while the second one behaves correctly.
My other machines don't behave like this at all. Until the problem
is undertood, let's go back to the original code.
