These are only present on boards with the AT90USB646 microcontroller (Lite, Launch 2).
Pin PE1 will be grounded if a numeric keypad is present.

Can use USB7206 or USB7006 any PCB, USB7216 on any PCB >= Launch 1.1. Note that USB7006 is only Gen 1 USB.
- USB7206: original, do not install R18, R28 if using, Gen 2 (10 Gb/s)
- USB7216: alternate, install R18, R28, Gen 2 (10 Gb/s), has built Type-C support for 1 port which we are not using to retain ability to use USB7206.
- USB7006: alternate, do not install R18, R28 if using, Gen 1 (5 Gb/s)
NXP introduced the PTN5110NHQZ and discontinued all others in the PTN5110 line. It defaults to a toggling dual role port, will need to be configured by software for the downstream facing ports. The upstream facing port should select the correct mode. No hardware changes are required.
- PTN5110THQ: original for downstream ports (U12, U13), defaults to sourcing power
- PTN5110DHQ: original for upstream port (U11), defaults to sinking power
- PTN5110NHQZ: replacement, defaults to dual role port, same part used all 3 locations
Changes were all due to availability problems. Each part only works with the listed PCB revisions.
