Crate rockusb 

Rockchip usb protocol host implementation

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 implementations of IO using libusb or nusb.

Printing chip info using libusb backend:

let devices = rockusb::libusb::Devices::new()?;
let mut device = devices.iter().next()
    .ok_or_else(|| anyhow::anyhow!("No Device found"))??;
println!("Chip Info: {:0x?}", device.chip_info()?);
Ok(())

Printing chip info using nusb backend:

let mut devices = rockusb::nusb::devices()?;
let info = devices.next()
    .ok_or_else(|| anyhow::anyhow!("No Device found"))?;
let mut device = rockusb::nusb::Device::from_usb_device_info(info)?;
println!("Chip Info: {:0x?}", device.chip_info().await?);
Ok(())
