4.4 Host Generic Services
The USB host generic services component (ti.biosusb.host.jos.a674) provides the services
to the other components in the USB host stack architecture. It provides services for memory
allocation, task management and initialization.
4.5 Platform Abstraction and Native OS Abstraction
The platform abstraction and native OS abstraction provides abstraction to the platform
features and operating system interfaces. This component provides isolation to the other
components of the host stack architecture from platform, native operating system and
allows portability of the host stack components.
4.6 Host Stack Component Libraries and Dependencies
Table 1 lists the host stack components and the corresponding libraries included in the
BIOSUSB deliverable. Note: The host stack component libraries are located at biosusb\host.
