usb: increase timeout to detect slower usb storage devices
What changed, and why it matters
This commit simply waits longer (about 3 seconds instead of 1 second) before showing a 'please insert USB device' prompt when a user plugs in a slow USB storage device. It is a usability fix, not a security fix.
No security action required; treat as a normal usability/compatbility patch.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change increases a retry counter from 5 to 15 in the USB mass-storage detection loop. Each iteration waits 200 ms, so the total detection grace period extends from ~1 s to ~3 s before the UI prompts the user. There is no change to parsing, authentication, cryptography, or trust boundaries.
