Looking for some way to determine if a USB-C port supports Alt Modes

Had a discussion with a friend about USB-C Alt Modes. That got me wondering - does anyone know of a way within Windows or via a utility to determine if any USB-C ports on a system support Alt modes, and if so, which modes the particular port supports?

As an example, in order to support DisplayPort video over USB-C, the port in question must support the DisplayPort Alternate USB-C mode.

Up until now I've simply relied upon the manufacturers specs, but surely there must be some way to determine this via software.

Thanks, dalchina. Yeah, I'm aware of those items. Just was curious to see if there was some sort of software that could report on that.

I find USB-C a bit frustrating at times. Another good example is the cables. If you grab a cable and look at it, unless it has clear markings, and many don't, you have no way to know if it supports 30W charging, 65W charging, 100W charging, 5Gbps data rates, or 10Gbps, 20Gbps, etc.

EDIT: My solution has been that when in doubt, grab a 100W 40Gbps thunderbolt cable. Then you are guaranteed the highest possible data rates and largest available current to power hungry devices.

Wow, thanks for that link. I've been looking for something like that. Have not looked at prices, but I'm sure that is very expensive equipment. Would love a consumer level device that does something like that.
