Recommended power settings for USB3 cameras

@David, long time no see =)

Thanks for the question. Actually that might be a good topic for our online help.

I would suggest to open the “power options” for windows and check the following points:

PCI Express

  • Link state power management = OFF

If you are using a PCI-Express card there might be also a driver option regarding the power management.

USB settings

  • USB selective suspend setting = Disabled
  • USB 3 Link Power Management = Disabled

Note that the USB 3 Link Power Management settings are only available for Windows 10 (I think also Windows 8 maybe) but they are hidden and you have to change your windows configuration to see those settings.

One way to do that would be to use the command promt and send the following command:

Show

powercfg -attributes 2a737441-1930-4402-8d77-b2bebba308a3 d4e98f31-5ffe-4ce1-be31-1b38b384c009 -ATTRIB_HIDE

Hide

powercfg -attributes 2a737441-1930-4402-8d77-b2bebba308a3 d4e98f31-5ffe-4ce1-be31-1b38b384c009 +ATTRIB_HIDE

There might be other options of course. Just google it ^^

Processor power management

  • Minimum processor state = 100 %

Regarding your system there might also be some relevant BIOS settings…
