the computer.
Reinstall all USB devices, check cable
connections, and then restart the computer.

installed, remove the modules, reinstall
one module (see page 65), and then restart
the computer. If the computer starts

module or reinstalled all modules without
error.
• If available, install properly working

requirements exist (see page 63).
