Last change on this file since 2391aaf was 2391aaf, checked in by Lubos Slovak <lubos.slovak@…>, 14 years ago

Huge refactoring of USB HID driver.

  • Created generic USB HID device structure and API (hiddev.h/c).
    • The structure holds data common for all HID devices.
    • Functions for creating the structure, and initializing based on given endpoint description.
    • Processing of descriptors, initializing of pipes moved here.
  • Modified USB HID keyboard device structure (kbddev.h/c).
    • This structure now holds only keyboard-specific data.
    • API provides function for adding device of type keyboard.
    • All keyboard-related functions moved here. These include:
      • IPC handler
      • Key and modifier processing functions
      • Polling
      • Creating new fibril for polling.
  • Separated USB HID class-specific request functions (hidreq.h/c)
  • Removed unused code from scancode parser (conv.c)

WARNING: not compileable due to a strange error.
  • Property mode set to 100644
