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 are connected securely. Check that
the connecting USB port on your computer is functioning correctly. If not, try connecting to 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?
Make sure that the combined power draw of devices connected to the ports does not exceed 2.4
A. If a port becomes overloaded, this message will appear on your computer. Reset the DUB-H7
by disconnecting both the power adapter and the USB cable connecting the DUB-H7 to your
computer for 5 seconds before plugging both cables back in.
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 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 OR SIMILAR DEVICE DOES NOT CHARGE?
Make sure the power adapter is connected to the DUB-H7. If your iPad displays a "Not Charging"
status, it will charge at a slow rate. You can check that the DUB-H7 is in Fast-Charge Mode (green
LED) by removing the USB connection from the DUB-H7 to your PC.
