Remove the UM100C from your laptop. When removing the UM100C,

5.3.6 Using the USB Modem Extension Y Cable
The UM100C Modem package includes an extension USB Y-shaped cable.
Although the Y cable is not required for use with your UM100C Modem,
it offers increased performance for your UM100C Modem under certain
operating conditions. Connect the Y cable to two separate USB ports of
your computer to deliver sufficient power when needed to increase RF
performance, and to solve clearance issues.
Using the USB Modem Extension Y Cable:
1) Plug the single end of the Y-shaped cable into the UM100C Modem. [A]
2) Depending on the condition you are trying to solve (increased RF performance,
or clearance issues), plug either one of the two connected ends of the USB
modem extension Y cable into the Type A USB port(s) on your computer. [B]
Note: The USB modem extension Y cable connector labeled #1, is the primary
data power cable used to either extend the UM100C modem away from your
computer allowing you to locate the modem in a more optimum signal location
or solve any computer USB port clearance issues. The USB modem extension
Y cable connector labeled #2, is a power boost Y cable and must be used with
connector #1 to provide the modem up to 1Amp of current for use in weaker signal
areas. Must be connected to two separate USB ports.
