TrOUBLESHOOTING
SETUP AND CONFIGURATION PROBLEMS
1. WHAT DO I DO IF MY COMPUTEr DOES NOT DETECT MY DUB-H7?
Check and ensure that all cables and the power adapter is connected securely. Check that
the connecting USB port on your computer is functioning correctly. If not, try connecting via an
alternative USB port on your computer.
2. WHAT DO I DO IF I GET A "USB HUB CUrrENT LIMIT ExCEEDED" MESSAGE IN
MICrOSOFT WINDOWS?
If a port becomes overloaded, this message will appear on the computer monitor. Reset the
DUB-H7 by pulling out the hub-to-computer USB cable and the power adapter for 5 seconds
before powering it back on.
3. HOW CAN I USE FAST-CHArGE MODE WHEN MY PC IS IN HIBErNATE MODE?
Some PCs don't support fast-charging in hibernate mode, because they don't switch off their
USB ports when they go into hibernate mode. To check if your PC does support it, connect the
DUB-H7 to the PC before putting the PC in hibernate mode. If the DUB-H7's LED doesn't turn
green when the PC goes into hibernate mode, your PC doesn't support Fast-Charge Mode while
hibernating. If this is the case, simply disconnect the DUB-H7 from the PC to activate Fast-
Charge Mode.
4. WHAT DO I DO IF MY DUB-H7 DOESN'T AUTOMATICALLY GO INTO FAST-CHArGE
MODE WHEN MY PC SHUTS DOWN?
Go into the PC's BIOS setup and disable the "Keyboard/Mouse Boot" option. Please note that
some PCs do not support automatic mode change when they shut down. If that is the case with
your PC, simply disconnect the DUB-H7 from your computer to let your DUB-H7 go into Fast-
Charge Mode.
5. WHAT DO I DO IF MY IPAD
Make sure the DUB-H7 is in Fast-Charge Mode (green LED), and make sure the device is
plugged into one of the black ports.
