fix: simplify usb listing (#1402)

elibosley · web-flow · commit 5355115af2f4 · 2025-05-22T13:42:26.000-04:00
## Summary by CodeRabbit - **Refactor** - Improved USB device detection for increased reliability and performance. - Device names are now displayed based on basic device information, with unnamed devices labeled appropriately. - GUID generation for devices is simplified and more robust.  --- - To see the specific tasks where the Asana app for GitHub is being used, see below: - https://app.asana.com/0/0/1210189043307638
