Tablet computing devices without pogo pins connect to keyboards via Bluetooth or micro-USB. These connectivity options have certain problems - Bluetooth consumes additional power and often has connectivity problems, while micro-USB keyboards exclusively occupy the USB port, which makes simultaneous charging of the tablet or use with other accessories impossible.

USB-C enables simultaneous fast charging and data transfer over USB. Leveraging USB-C technology, this disclosure provides techniques that enable tablets with USB-C port to reliably connect to a keyboard for simultaneous USB-based fast charging and access to other USB accessories.
