Rockchip bootroms and early loaders implement an USB protocol to help loader early firmware, flashing persistant storage etc. This crate contains a sans-io implementation of that protocol as well as an optional (enabled by default) implementation of IO using libusb
fn main() -> anyhow::Result<()> {
let devices = rockusb::libusb::Devices::new()?;
let mut transport = devices.iter().next()
.ok_or_else(|| anyhow::anyhow!("No Device found"))??;
println!("Chip Info: {:0x?}", transport.chip_info()?);
Ok(())
}
