It all depends on what you mean by writing "usb activity". Technically speaking, there is always USB activity between a connected USB device and the USB host. USB is a protocol that is making heavy use of polling, with the USB host continuously polling connected USB devices with a frequency between 125 Hz and 1000 Hz. In other words, there would be no need attempting to detect USB activity because there is always USB activity between the USB host (computer) and connected USB devices.
