 ### 7. Missing standard control requests (simulated devices)
 - **File:** `lib/src/device.rs:346-778`
 - **Issue:** `GetStatus`, `ClearFeature`, `SetFeature`, `GetConfiguration`, `SetAddress` are unhandled for simulated devices.
-- **Status:** [ ] TODO
+- **Status:** [x] DONE — Added GetConfiguration, GetStatus (device/interface/endpoint), ClearFeature, SetFeature, SetAddress handlers.

 ### 10. `server()` panics on bind failure
 - **File:** `lib/src/lib.rs:773`
 - **Issue:** `expect("bind to addr")` panics instead of returning `Result`.
-- **Status:** [ ] TODO
+- **Status:** [x] DONE — Changed return type to `Result<()>`, replaced `expect` with `?`.

 ### 13. `debug_assert` for path/bus_id length
 - **File:** `lib/src/device.rs:252-260`
 - **Issue:** `debug_assert!` compiled out in release; silent truncation if path > 256 bytes.
-- **Status:** [ ] TODO
+- **Status:** [x] DONE — Replaced `debug_assert!` + `resize` with `truncate` + `resize`.
