While troubleshooting why a generic $19.99 Multiport (USB, HDMI, Type-C) Type-C dongle didn't work on Scarlet, I noticed that Vconn Req and Vbus Req were both set to zero in the AMA VDO. For a better user experience, default to Vbus ON if both Vconn and Vbus Req are both zero. BUG=b:78286905 BRANCH=NONE TEST=manual Tested the generic dongle with USB-Keyboard, TypeC power adapter, and HP monitor.
