Systemic fix: all local recipes (~150 references across 40+ Cargo.toml files)
now resolve libredox, redox_syscall, and redox-scheme through
recipes/core/base/ symlinks instead of local/sources/ paths.
Eliminates lockfile collision between Cargo's resolution of the same
package through different path strings (local/sources/ vs recipes/core/base/).
This is required because the base recipe's workspace Cargo.toml resolves
these deps through recipes/core/base/ (via symlink chain from the
recipe copy location), and Cargo treats different path strings to the
same directory as different packages.
usb-core spawn.rs:
- class_driver_for_usb_class() extended to cover all Red Bear class drivers:
Audio(0x01)→redbear-usbaudiod, CDC ACM(0x02/0x02)→redbear-acmd,
CDC ECM(0x02/0x06)→redbear-ecmd, HID(0x03)→usbhidd,
Mass Storage(0x08)→usbscsid, Hub(0x09)→usbhubd,
Vendor(0xFF)→redbear-ftdi
- Subclass-aware matching (Audio Control vs Streaming, CDC ACM vs ECM)
- is_trusted_usb_driver() whitelist extended with all 7 driver binaries
- Test suite updated with new assertions (11/11 pass)
redbear-usb-hotplugd:
- DRIVER_MAP extended to 11 entries with subclass-aware matching
- Recursive port scanning: scan_ports_recursive() traverses child
hub port directories (handles port1.port2.port3 paths)
- extract_port_id() parses full port paths to extract controller
name and port string for child hub ports
- Protocol-aware extra arg: Storage passes protocol byte (0x50/0x62),
all other classes pass interface number
- Skips CDC Data interfaces (0x0A) and hub interfaces (0x09) when
reading descriptors — matches Linux's interface matching logic
- Improved disconnect detection via descriptor accessibility heuristic
- Cleaner structure: find_driver(), scan_controllers(), scan_ports(),
try_read_descriptors(), main loop with connect/disconnect tracking
All 7 Red Bear USB class drivers now auto-spawning on device connect:
usbhidd, usbscsid, usbhubd, redbear-acmd, redbear-ecmd,
redbear-usbaudiod, redbear-ftdi
Cross-referenced with Linux 7.1 drivers/usb/core/hub.c port event
handling and drivers/usb/core/driver.c device-driver binding.
New daemon (216 lines) that watches USB controllers for device
attachment/detachment and auto-spawns the appropriate class driver.
Architecture:
- Polls /scheme/usb/ every 1000ms for controller directories
- For each controller, enumerates root hub ports
- Reads device descriptors (class/subclass/protocol) via XhciClientHandle
- Maps class to driver binary: HID(0x03)→usbhidd, Storage(0x08)→usbscsid,
Hub(0x09)→usbhubd
- Spawns driver with <scheme> <port> <protocol> arguments
- Tracks spawned Child processes in HashMap<port_path, TrackedDevice>
- Detects disconnection (descriptor read fails) → kills driver + removes
from tracking
- Detects driver exit (try_wait) → removes from tracking
- Skips hub interfaces (usbhubd handles its own children)
Config:
- Added to redbear-mini.toml (inherited by redbear-full)
- Auto-started via 02_usb_hotplug.service (oneshot_async, after base.target
and pcid-spawner)
Driver map supports: HID (0x03), Mass Storage (0x08 with BOT protocol),
Hub (0x09). Additional class drivers extendable via DRIVER_MAP constant.
