USB ECN for 5.5V VBUS?

(1/1)

rounin:
I downloaded the USB 2.0 spec from here today, https://www.usb.org/document-library/usb-20-specification, and found a "USB ENGINEERING CHANGE NOTICE, USB 2.0 VBUS Max Limit" that says VBUS may now be as high as 5.5V as part of some changes for type C.

This worries be a bit, I just did a device with a 5.5V max LDO, thinking since we protected it and slew limited the inrush it would be plenty of margin.

Is this real? Any devices in the wild with a higher VBUS than 5.25V?

rounin:
http://www.testusb.com/power_issue.htm mentions testing up to 5.5V. Maybe the general population (eg wikipedia) is just out of date when listing VBUS max as 5.25V.
