D.2.3

Hot Plug

OpenBoot PROM at present doesn't support hot plugging of USB devices. If a
user removes the USB keyboard when the system is at the OK prompt, the system
will become wedged. If the USB keyboard is plugged into the system again
OpenBoot PROM will not recognize the keyboard. You will have to power cycle
the system.
As a general rule, no USB device should be hotplugged when the system is at the
OK prompt in OpenBoot PROM and during booting of the system until a UNIX
login prompt is displayed.
Unplugging open or busy device will not remove the entries in the prtconf file.
The system prompts to plug in the original device. To clear the prtconf entries,
the original device needs to be plugged into the same port, the application
terminated, and then the device removed. Until then, the port remains unusable.
After plugging in a device, check prtconf or /dev/usb before hot removing.
D.2.4

Cabling

Never use USB cable extenders that are available on the market. Always use a
hub with longer cables to connect devices.
Always use fully rated (12 Mbps) 20/28 AWG cables for connecting devices.
