### USB Controller
Build:
```
cd contrib
make run
cd hw/usb_interface/ch552_fw
make
```
To flash the controller you need hardware like the [Blinkinlabs CH55x
Reset
Controller](https://shop-nl.blinkinlabs.com/products/ch55x-reset-controller)
and a USB-A to USB-C converter.
[Reset Controller source](https://github.com/Blinkinlabs/ch55x_programmer).
You also need [chprog](https://github.com/ole00/chprog).
1. Connect the Reset Controller to your computer through the "DUT\_IN".
2. Connect the TKey to "DUT\_OUT".
3. Press the "BOOTLOADER" button.
4. Run `make flash_patched` in `hw/usb_interface/ch552_fw` outside of
a container.
