This page aims at providing information about the linking protocols of the HP Prime.

The TI-Nspire uses vendor-specific class and proprietary protocols which require specific drivers; the Casio Prizm uses MSD, and the HP Prime uses standard classes as well. Standard classes which do not require extra driver installs are a boon to users.

High-level USB behaviour

"Normal" mode

In normal mode, the Prime exposes itself as a Human Interaction Device (HID). That's a standard class, with built-in drivers in pretty much any USB-supporting OS, aimed primarily at mice, keyboards and joysticks; lots of manufacturers (ab)use that class for other purposes.

Reflashing mode

In reflashing mode, the Prime exposes itself as a Mass Storage Device (MSD), another standard-class with built-in drivers.
