Well, you may try to create some CPU load. (This is no joke, we found a similar problem with one of our quad cores.) In this case, the CPU wakes up and does not slow down the USB bus for power saving. Search in the internet for "cpustress" tools for generating CPU load.

I also suggest to ask the camera manufacturer for support.
