If you are experiencing problems with one of the front panel ports, you might be able to try your device
in the corresponding port on the back side of the computer. If this does not fix the problem or you must
use the front panel ports, continue troubleshooting.
Some problems in this section are also discussed in other troubleshooting suggestions in this chapter.
