Fix USB HID errors during browser refresh 

When browser refreshes (Shift+R), USB state changes from "configured" to
"default" temporarily. Previously, HID files remained open with stale file
handles, causing "transport endpoint shutdown" errors.

Now proactively close HID files when USB transitions away from "configured"
state, preventing writes to invalid endpoints.

Fixes USB HID transport endpoint shutdown errors during browser refresh.
