USB-A full-speed cable still sold for legacy gear; commodity but not dollar-store free. (as of 2026) Source: Manual US retail band for a ~1 m cable that supports this data tier (2026). Not host port BOM cost; not no-name bulk bin fantasy.
Status
Kept so older equipment still works. Rarely the starting point for new products.
Capabilities
- Data - This tier is rated for more than charge-only use.
Notes
Original USB 1.0 shipped in 1996; USB 1.1 is the revision that actually became common. Same Type-A shell as later USB 2.0.
