fix(device): resolve hanging issue in USB device discovery

- Remove problematic caching and retry logic that was causing hangs
- Device discovery now works reliably and returns USB devices immediately
- The `usbipd list` command now functions correctly and displays connected USB devices
- Maintains queue synchronization for thread safety
- Fixes issue where device enumeration would hang indefinitely

Tested with USB device connected:
- Successfully discovers and lists USB devices
- Proper vendor ID, product ID, and device name extraction
- Linux-compatible bus ID generation works correctly
