embedded-usb-host

An all-in-one host-side Rust USB stack implementation destined for embedded (no_std) use.

Includes host driver for SAMD chips (for now).

Includes class drivers for keyboard and MIDI devices.

Status

Work in progress, alpha-level code but compiles and runs.

Confirmed working with classic Dell SK-8115 keyboard, see examples/bootkbd

Also See https://github.com/fralalonde/usbmidi-host for sample MIDI application.

Not yet published on crates.io for obvious maturity reasons.

Missing

Concurrent, non-blocking transfers (yep, still all single threaded now)
STM32, RP2040 support would be nice
Get string descriptors from device (forked UTF16 is ready!)
More class drivers (Hub, Mouse, etc.)
Alternative Async API
Harmonize with usb-device crate for full OTG madness

Known bugs

Double fault on device reconnect (this is new)
MIDI not coming in (Arturia Beatstep)
HP keyboard (KU-1156) fails to get descriptor, why?
