USB Support: PA-RISC Firmware • PDC/IODC has been updated only for SPUs with built-in USB. • Firmware searches for a keyboard on the USB controller path specified (by default, the built-in controller, but PCI-USB cards are addressable). • At initial release, the console keyboard must be one of the first seven devices found. If it is connected directly to the host, or there is only one 4-port or 7-port hub in use, it will be. • Firmware accepts input from the first keyboard found, in a breadth-first search for the keyboard topologically closest to the processor. • Only "HID Boot" devices are eligible for boot console. Any device, such as a USB numeric pad, that identifies as "HID boot", but is not a full keyboard, needs to be located beyond the console keyboard in the topology. • Hot detach-reattach is not supported. The SPU must be rebooted if the keyboard is disconnected during boot. • If no keyboard is found, firmware seeks console on the first serial port.
