Usually this is a result of the USB power settings in Windows. Windows has the ability to limit the amount of power it allows out of any USB port. This leads to the camera not getting the power it needs from the USB port to allow for un-interrupted video signal. Following this guide should make it so Windows does not limit the power out of your USB ports. 



1. Global Suspend - Global suspend is only an option in Windows Vista and newer. In older Windows OS, you can skip to step 2, below.


a. Go to “Control Panel” -> “Power Options.” 


b. Go to “Change plan settings” on the power plan in use. 


c. Set “Put the computer to sleep” to “Never.” 


d. Go to “Change advanced power settings.” 


e. Set “Advanced settings” -> “USB settings” -> “USB selective suspend setting” to “Disabled” 

f. Click “OK” to apply settings and close. 

2. Individual USB Hubs and Extension Devices:

This setting must be applied in addition to the “Global Suspend”. All hubs and extension 

Tx and Rx devices must have their individual power management disabled. This must be 

done with devices connected to the host. On Windows XP and earlier, this is the only 

setting to be applied, as Global Suspend (1. Above) is not an option. 

a. Open device manager. 

b. In the menu, select “View” -> “Devices by connection.” 

c. Select the topmost element in the list (the name of your host) and type the ‘*’ key to fully expand the entire list. 

d. Locate your USB 3.0 eXtensible host controller in the list. 

e. Identify the hubs, Tx and Rx units may show up as hubs (they will be two hubs connected together). 

f. Connecting a device to the extension or hub can help remove ambiguity.  

g. Right click on each “hub” and select “Properties.” 

h. Select the “Power management” tab and deselect the box labelled “Allow the computer to turn off this device to save power” and click “OK.” 

i. If the “Power Management” tab does not exist, the device will not be 

j. Repeat step 2.g and 2.h for any hubs, Tx or Rx units attached to the computer. 

k. Connect the same systems to any other 3.0 ports and repeat the above steps 2.g through 2.i, if there is a possibility that you will use other USB 3.0 ports on the PC. Suspended and should work fine.

If applying these setting does not fix your disconnecting issue, please try and connect your camera directly to your computer without any USB extensions or USB Hubs in place to see if the issue goes away. If it does, then your issue most likely lies with the USB extension cable you are using. Please contact the manufacturer of your cable and they should be able to get you a replacement cable.
