Failed to Send a USB control request!

Technical Support & Q&A

Hello,
I’m using OpenNI2 and today a sensor started throwing an exception when I try to call Device.open:

java.lang.RuntimeException: 	Could not open "2bc5/0404@2/4": Failed to send a USB control request!

	at org.openni.NativeMethods.checkReturnStatus(NativeMethods.java:74) ~[org.openni-1.0.0.jar!/:na]
	at org.openni.Device.open(Device.java:70) ~[org.openni-1.0.0.jar!/:na]

I’m not sure how to troubleshoot this type of error - any help would be appreciated.

Unplugging and replugging helps most of the time in my case, but that is really annoying and I didn’t find any other solution until now.
