NI USB Devices May Not Wake from Hibernation



Hardware: Multifunction DAQ (MIO)>>Portable>>USB-9211, Multifunction DAQ (MIO)>>Portable>>USB-9215

Problem:
My computer has gone into hibernation and upon waking, my NI USB device no longer seems to respond. What can I do to fix this?

Solution:
When waking from hibernation, USB devices might not respond. To resume operation, you either have to "refresh" devices in Windows Device Manager, or unplug and reattach the device. Hibernation behavior varies depending on the system and USB topology. In some cases, the device never turns off because the hub may keep the power turned on, and the device resumes as expected. However, in cases where power to the device is turned off, the device might not resume functioning.

As a general rule, try and prevent the system from going into hibernation when an NI USB device is plugged in, as unexpected behavior may result. To disable power management, complete the following steps according to your OS:

Windows 8: 
To prevent the computer from going into hibernation mode, click the Desktop tile on the start screen.  From the desktop window, move the mouse to the bottom right corner of the screen to open the Charms bar.  Navigate to the Control Panel (Settings » Control Panel).  From the Control Panel, navigate to the Power Options Window (System and Security » Power Options). Next to the power plan you would like to change, select Change plan settings and then select Change advanced power settings.  In the resulting window, expand sleep and then expand Hibernate after and set it to Never. 

Windows 7:
To prevent the computer from going into hibernation mode, navigate to the Power Options dialog(Start » Control Panel » Power Options).  Next to the power plan you would like to change, select Change plan settings and then select Change advanced power settings.  In the resulting window, expand sleep and then expand Hibernate after and set it to Never.

Windows XP:
To prevent the computer from going into the power save modes, navigate to the Power Options dialog box (Start » Settings » Control Panel » Power Options) and disable the System standby and System hibernates options on the Power Schemes tab.

Windows 2000/ME:
To prevent the computer from going into the power save modes, navigate to the Power Options dialog (Start » Settings » Control Panel » Power Options) and disable the System standby option on the Power Schemes tab. To disable hibernation, select the Hibernate tab and deselect the Enable hibernate support option.
