Can I Connect a USB-C to a USB 2.0 Port?
Can I connect a USB Type C cable to an older USB 2.0 port?
No you cannot.
The USB type C socket is a backward compatible technology with respect to the protocol but it is not backward compatible in the physical connection. Meaning, the sockets wont fit, but with an adapter you will have no problem charge devices or trasnfering data.
The USB-C connection was design for several reasons. Of course a new specification will always be developed to increase data transfer rates or introduce new features, such as increased power across the buss to charge or power connected devices. The main reason for USB-C connectors is size. With USB being the world’s most popular technology for peripheral devices, the Implementers Forum (with members such as Intel, Acer, AData, SanDisk, Lexar, Micron and many others) they wanted to insure the USB specification continued to be the #1 method for connecting the ever decreasing size of digital devices.
