E-4 Sun Blade 150 Service Manual • June 2002
■ 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.
E.2.5 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.
