XUSM is the XENTRY Update Service Messenger — Mercedes-Benz's official distribution library for control unit software and XENTRY release updates.
Yes. Downloads are streamed from Mercedes-Benz's own CDN (xentryupdateservice.i.mercedes-benz.com) and verified by SHA-256 against the catalog.
The legacy and MB.OS catalogs hold tens of thousands of files, so the search needs at least 3 characters. Release updates are few enough to list in full.
Access tokens are refreshed automatically. Individual files in the catalogs change as Mercedes-Benz updates them; search results always reflect the live library.
