usbfs_snoop logs traffic going via the usbfs filesystem. This filesystem allows userspace programs to drive USB devices, but isn't used at all by kernel drivers. So you won't see anything if the device's driver is a kernel module, which looks to be the case here. I think there's something called usbmon (?) which sounds more like what you're looking for.
