HID Utilities

HID Utilities

Apple HID Utilities is an API built on top of Apple HID Manager. It is provided as free software which can be used or modified. The aim was to create a higher level API than HID Manager for developers to more rapidly develop applications which use USB HID devices but do not need the flexibility of the lower level HID Manager.

Problems

It was designed with games in mind, so it can limit flexibility for other situations. It uses its own list of devices, and creating that list can take create a high load on the computer. Internally, it uses a number of global variables, which means that multiple instances connected to the same device queue will steal events from each other.
