USBLC6-2SC6

The KiCad symbol on this page types pin 2 (GND) as passive. A ground pin is a power input, so KiCad's ERC can't flag it as undriven, and adom-aiflow's schematic check warns ("power pin GND is passive; declare it power_in"). I retyped it to power_in in a local copy for a board using this part; the other pins (I/O 1, 3, 4, 6 and VBUS 5) look right. Suggested fix: (pin power_in line (at 0 -7.62 90) ...) for GND.
