23 The type-C connectors are reversible, so the actual communication might
24 happen on CC1 or CC2 depending the polarity of the plug inside the receptacle.
29 Captured Between a Google Pixel 2015 laptop and both its 5V/12/V/20V power
30 supply and an USB-C to HDMI video dongle.
32 The sigrok command lines used were:
34 sigrok-cli -d chromium-twinkie --continuous -o power_supply_20V.sr
35 sigrok-cli -d chromium-twinkie --continuous -o hdmi_dongle.sr
