I'm not aware of any issues with such devices. For the printer problem you should probably send a detailed bug report to linux-usb <linux-usb@vger.kernel.org> For the mtp regression you should probably first try to pinpoint the cause, try downgrading the kernel to a known working f20 kernel, if that does not help, the cause likely is some userspace component (e.g. libmtp).
