USB Support: HP-UX Kernel (cont.) USB Class Drivers supplied at initial release: • Hub: Root and external • HID: Human Interface Device Note that thunking makes USB "boot" devices appear to be PS/2. Class Drivers under investigation (but not yet committed): • Communication: For serial adaptors primarily. WAN attach might be addressed, but LAN is a non-objective, given that USB is slower than 10BaseT. • Printer: However, it may be trivial, mainly because Unix has no GDI. Further, at the I/O port level, HP-UX presumes only a raw data stream (lprpp(1M) handles EOL mapping, and the app or spooler is responsible for the PDL). The USB-parallel adaptors tested so far simply work, once the device file is created. Class Drivers under consideration: • Audio: For external speakers primarily. • Imaging • Mass Storage • Monitor Control (in HID Class)
