External USB Modems
21
Possible solution:
If the modem has worked previously and you removed the USB cable
from the computer and then reattached it, try another USB port. It may
have been set up originally on the other USB port. You should notice
some minimal activity from your computer such as hard disk activity or an
hour glass icon for a few seconds when you insert or remove a USB cable
from the computer or the USB device. If you do not see anything, your
system may not be properly communicating with the USB ports.

Modem as a Serial

Possible solution:
You may be using a COM port that is either already in use or not
configured correctly. To work properly, this modem needs to be plugged
