In Agent mode, I’ll organize the GL3520 terminals by function, set logical sections and pin groups, and adjust pin orientations and terminal order for a readable symbol. I’ll preserve pin numbers and connectivity and verify the updated organization.

I’ll inspect the terminal definitions, organize them by USB port and support function, and verify that pin numbers and footprint mappings remain unchanged.

Organized all 89 terminals into functional sections and pin groups, with upstream/support pins left, downstream ports right, power top, and ground/NC bottom. Terminal order is unique within each section, differential pairs remain adjacent, and pin names, numbers, electrical types, and footprint mappings are unchanged.

Display limitation: the current renderer omits section headings and shows downstream sections in 1–4–2–3 order despite the assigned metadata.
