I have an Android phone with a USB-C port. My new Windows 10 desktop computer also has a USB-C port.

My old cables plugged into my phone and computer (Via a USB-A port just fine, and everything behaves just as I expect. Just like my last computer, my phone gets recognized by the computer in less than a second (I hear a noise on the computer once it's connected.

To get faster data transfer rates and charging rate, I decided to get a USB-C to USB-C cable. When I plug in the phone using USB-C to USB-C, it takes 10-30 seconds to get recognized by the computer (and the phone according to the new "Charging Rapidly" message on the lock screen).

Why does it take so long? Is there anything I can do to speed it up?

I tried to do a little research online, and the closest thing I could find was to check with something about Bluetooth settings, but as best as I can tell, my new computer doesn't have Bluetooth.

    Could be some difficulty in Power Delivery negotiations, some timeouts due to not very matched profiles... Did you try any other less sophisticated Type-C devices, like a flash drive? Does it also take that long? – Ale..chenski Apr 23 '19 at 19:13
  • @Ale..chenski That's good enough to be an answer. I haven't tested it yet, so I'm not sure it's the accepted answer yet, but it's worth at least an answer upvote. – McKay Apr 25 '19 at 3:14
