technical support and service they receive falls far short of their
expectations—and certainly isn’t worth what they paid.

USB 2.0 specifies three types of connectors: the A connect-or,
the B connector, and the Mini B connector. A fourth type of
connector, the Mini A (used for smaller peripherals such as mobile
phones), was developed as part of the USB OTG specification.
