S o lu t i o n 2 :
When you insert or remove a USB cable from your computer, the com-
puter should indicate activity such as hard disk activity or an hourglass
cursor. If the computer does not show any sign of activity, your system
may not be properly communicating with the USB ports. Try these tech-
niques to determine whether the ports are communicating properly:
1. Try using a different USB port on the computer. If you are using a
USB hub, try using a USB port on the computer instead.
2. If the modem has worked previously and you removed the USB cable
from the computer and then reconnected it, try another USB port.
The modem may have been installed originally on the other USB port.
3. Your USB port may not be enabled. To ensure that USB is enabled
on your system:
A. Go to the device manager:
Windows Vista:
1) Click Windows Start > Control Panel > System and Main-
tenance > System.
2) Under Tasks, click Device Manager.
Windows XP:
1) Click Windows Start > Control Panel.
2) Double-click System.
3) On the Hardware tab, select Device Manager.
Windows 2000:
1) On the desktop, right-click My Computer and select Proper-
ties.
2) On the Hardware tab, click Device Manager.
Windows Me or 98:
1) On the desktop, right-click My Computer and select Proper-
ties.
2) Select the Device Manager tab.
