It contains the following functions: * termux_usb_get_device_list * termux_usb_free_device_list * termux_usb_open * termux_usb_get_config_descriptor * termux_usb_free_config_descriptor These functions are replacements for the corresponding libusb_* functions, kind of. The termux variants uses structs like struct termux_usb_device and struct termux_usb_config_descriptor that are similar, but not identical, to libusb_device and libusb_config_descriptor. They work by calling termux-api and get back information about devices and configs as a protobuf stream. The free functions also frees all array elements, whereas the libusb variants only frees elements that have a reference count of 1 or less. For the termux variants where do not keep track of the reference count, so information that should be kept around should be memcpy'ed or similar before termux_usb_free_* is called. termux_usb_open requires user interaction. It calls termux-api which opens the device through the android API, which shows a prompt to the user to accept or deny opening the device.

See the accompanying termux-api PR for the other side of the coin: termux/termux-api#759
I also have two test programs that I will incorperate in a testsuite later: https://github.com/Grimler91/termux-api-package/tree/usb-protobuf-with-test-programs
