USB-C has been on the market for a good few years now, and it’s finally starting to take over. Many new laptops only come with the newer port, making it difficult to use legacy USB-A devices. [Matt] doesn’t like mucking about with dongles and hubs, so set about converting some older hardware to the new standard. (Video, embedded below.)
[Matt] first set about hacking a Logitech wireless mouse dongle, peeling apart the original USB A connector to gain access to the PCB inside. A USB C breakout board is then sourced, and the relevant pins in the USB-C connector are soldered to the original USB-A connector pads. Unfortunately, the breakout board is configured as a host device, unsuitable for peripherals. Replacing a pull-up resistor with a pull-down on the VCONN and CC1 pins rectifies this. With the mod done, the mouse enumerates and is fully functional over USB-C. A little Sugru is then used to wrap everything up neatly.
[Matt] then progresses through several other similar mods to other hardware, sharing useful tips on how to make things as neat and useful as possible. It’s a tidy hack that could make your user experience with a new laptop much less painful. USB-C mods are becoming more common, and we’ve seen plenty done to soldering irons thanks to the Power Delivery spec.
