AI Summary

USB cables generally work without issue regardless of generation, but they must stay within length limits to maintain performance. The USB Implementers Forum (USB‑IF) specifies maximum lengths that vary by cable type, spanning roughly 16 feet for some cables down to about 3 feet for others. Although the USB‑IF is an industry group rather than a regulator, manufacturers can produce longer cables, but exceeding these guidelines may degrade signal quality. The limits serve as best‑practice recommendations to avoid performance problems.
