USB Type-B is the roughly square legacy peripheral connector with beveled upper corners.

USB Type-B engineering reference
USB-IF compliance guidance fixes Standard-B at four contacts. The connector form alone does not identify USB generation, peripheral function or supported transfer rate.

Source-scoped identification facts
Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Recorded variant and source limits
- No V54 contact numbering or electrical assignment map is published.
- Peripheral function, transfer rate and power behavior remain device-specific.
- USB 2.0 Series "B" receptacle/plug: Receptacle face per Figure 6-8: 2 upper-left, 1 upper-right, 3 lower-left, 4 lower-right.
- USB 2.0 Standard-B (Series B) receptacle/plug: Contact-number convention of USB 2.0 Table 6-1; physical layout per USB 2.0 Figures 6-7/6-8 (not re-read for spatial claims here).
- Prior view context (not a source-view value): Contact count only in V54; no numbered mating-face map is reproduced.
Pins & wiring
Pinout
Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.
What the status labels mean
- Confirmed
- Recorded research passes agree within this variant; this is not independent human review or hardware validation.
- Single source
- Only one underlying document, or one pass, supports this assignment.
- Device-specific
- Supported for the named equipment or wiring only. Check your device’s manual.
- Unverified
- Missing or conflicting evidence. Do not wire from this row.
- Not connected
- The source explicitly says NC, no contact or no pin for this wiring.
Unknowns stay unknown.
- No V54 contact numbering or electrical assignment map is published.
- Peripheral function, transfer rate and power behavior remain device-specific.
