TROUBLESHOOTING

SETUP AND CONFIGURATION PROBLEMS
1. WHAT DO I DO IF MY COMPUTER DOES NOT DETECT MY DUB-H4?
Check and ensure that all cables and the power adapter are connected
securely, and that the USB port on your computer is functioning
correctly. If not, try connecting to a different 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 A. If a port becomes overloaded, this message
will appear on your computer. Reset the DUB-H4 by disconnecting both
the power adapter and the USB cable connecting the DUB-H4 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-H4 to the PC before putting
the PC in hibernate mode. If the DUB-H4'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-H4 from the PC to activate Fast-Charge Mode.
4. WHAT DO I DO IF MY DUB-H4 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-H4 from your computer to let your DUB-H4 go into
Fast-Charge Mode.
5. WHAT DO I DO IF MY IPAD OR SIMILAR DEVICE DOES NOT CHARGE?
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.
