Troubleshooting
1. How can I check whether my PC supports USB2.0 or not?
You can check it in the “device manager” Select Start->Control panel->System-
>Hardware-> device manager then you will see a device is enrolled at “Universal Serial
Bus Controller”(Non-INTEL based main board may show a different name “standard-
extension USB host controller” instead of USB2.0. If you realize that your PC does not
support USB2.0, please purchase a PCI USB2.0 add-in card ( for laptop, you need a
PCMCIA USB 2.0 card)
2. Can I watch a HDTV show using BlueBox USB HD with USB1.1 connection?
No. you can not watch a HDTV show with USB 1.1 interface due to its very limited data
transmission rate (13Mbps or lower). However you are able to watch an analog TV
show with USB 1.1 interface.
3. What’s the maximum length of the USB2.0 cable?
The recommendation by the USB2.0 specification is 4.5M. However we do not
recommend the maximum length because the video data can be damaged by signal
interference with the length.
4. What should I be careful for the digital TV broadcasts?
Do not connect the other USB cable while running the BlueBox USB HD. It may cause

5. What kind of antenna do I need to use for the digital TV reception?
You need to use an UHF antenna for the digital TV reception. A VHF antenna also can
be used for the analog TV reception but not for the digital. Several indoor UHF/VHF
antennas are available at your nearer Electronics shop. Please make sure that your
residential area is not a blanket area. If you are in a blanket area, you can not watch
the digital TV broadcasts.
6. I can not see the LED light in the front panel of the BlueBox USB HD.
BlueBox USB HD has been designed to work with the Power and USB connection
simultaneously. So when you connect the power and USB cable to your PC(your PC
should be power-on), you can see the LED light in the front panel.
7. I have been using a desk lamp with the BlueBox USB HD on the desk. When I use
the remote control for the BlueBox USB HD under the light of the desk lamp,
sometimes the remote control does not work. Why does it happen?
The electric wave of the desk lamp may jam signal of the infrared remote control. We
recommend you to turn it off and use the BlueBox USB solely.
8. The screen is not in full size and screen noise happens in the bottom.
As TV stations have its own screen size, the screen size may differ slightly then use the
