A growing list of real-world USB-C cables, indexed by the identity their e-marker reports over USB-PD Discover Identity. Vendor names come from the bundled USB-IF list.

Patterns worth flagging
A few of the reports show patterns that the planned cable trust signals feature should pick up:
- Marketing claim outpaces e-marker capability. #49 (Dbilida) is sold as "Thunderbolt 4 / 40 Gbps / 240 W" but the e-marker reports passive USB4 Gen 3 with no USB-IF cert. The cable may carry the advertised data rate, but there is no cert backing the claim.
- Genuinely unregistered VID with no XID. #71 (UGOURD AliExpress) reports 80 Gbps USB4 Gen 4 from an unregistered VID and zero XID. Plausibly real silicon, but unverifiable from the e-marker alone.
- Zeroed identity fields. #61 (CUKTECH No.6) has a present e-marker that reports
0x0000for VID, PID, and no speed. Already flagged by trust signals today; the report confirms the pattern is real and not a parser bug.
