Fill Type-C VBUS and CC holes from CabCon R2.5 and R2.0 (2.76.0).

R2.5 keeps Rp/Rd/Ra, charger 4.75/4.0 V, zOPEN, tCCDebounce, tVBUSON.
R2.0 August 2019 Table 4-32 fills Source CC shall-detect only. vSafe5V stays UNKNOWN.

+USB Type-C Cable and Connector Specification Release 2.0 (August 2019) fills Source CC shall-detect voltages that R2.5 only illustrates as variance examples (Table 4-32 p.240: vRd 1.50 V, vOPEN 1.65 V, vRa 0.15 V). Type-C Current charger VBUS 4.75–5.5 V no-load / 4.0–5.5 V at 3 A, zOPEN 126 kΩ, tCCDebounce 100–200 ms, and tVBUSON 275 ms stay on newer CabCon R2.5 (Figure 4-39 / Tables 4-30, 4-32, 4-34). Rp/Rd/Ra unchanged. vSafe5V volt range still needs USB PD.

 ## 2.75.0 — 2026-09-22 — Protocol packs from USB 2.0 Rev 2.0 and Type-C CabCon R2.5
 
 USB 2.0 Base Specification (April 27, 2000) fills LS 1.50 Mb/s, FS 12 Mb/s, HS 480 Mb/s, pull-up/down, VBUS 4.75–5.25 V, LS/FS edges. Cable Z0 90 Ω is `source_type=CABLE`; HS PCB traces *should* 90 Ω is RECOMMENDED PCB — L2 `differential_impedance` stays UNKNOWN so 45/50 Ω fixtures are not treated as Zdiff. Type-C Cable and Connector Specification Release 2.5 fills Rp/Rd/Ra from Tables 4-27/4-28/4-29. VBUS volts still need USB PD vSafe5V. IEEE 802.3 Section One/Three and HDMI Adopter remain missing.
