Cheapest USB PIC18F

Currently that's PIC18F13K50[1] at $1.32 volume price, compared to
$3.44 for my default PIC182550.  Mouser pricing for 13K50 is [2]

1:	$2.39	
10:	$1.91	
25:	$1.75	
100:	$1.58

Bummer, reading the Flash programming manual[3] it looks like D+/D-
are multiplexed with PGC/PGD, which means PK2 approach can't be used.
Probably needs a bootloader to use Staapl.

Talking about bootloader, it might be simplest to go that route now
that USB is working.
