Native USB API for Rust

Heavily inspired by the C http://libusb.info driver.

Rust usbapi crate only support Linux ATM.

UsbAPI crate does not have any dependies on libusb C API's and is a clean implementation in Rust using ioctl/mmap calls on Linux using nix low level crate.

You are free to fork or send pull request and make it work on any of the below platforms.

Dependies

• serde
• serde-hex
• nix/libc
• mio

dev-dependies

Examples uses:

• signal-hook
• serde_json
• toml

Supported functions in Linux

• [X] Enumerate USB peripherals
• [X] Zero copy using mmap buffers.
• [X] Sync bulk/control API's
• [X] Async bulk transmissions
• [X] Descriptors implements serde for easy serializing to JSON, Toml etc...

TODO

When I started this project I was new in Rust. Some stuff need to be done better:

• [ ] USBCore should be done as trait(s) for easier porting to other platforms.
• [ ] Fix possible leak in sync_respond()
• [ ] Add isochronous support
• [ ] Use log crate instead of eprintln and println for debug.

For those who use any of below platforms, feel free to send a pull request:

• [ ] Support FreeBSD/OpenBSD
• [ ] Support NetBSD
• [ ] Support Haiku
• [ ] Support OSX
• [ ] Support Windows
