OK, I got it, maybe you should describe it as not working instead of sleep, which has specific meaning in linux kernel. And both your USB printer/HDD aren't in linux sleep state, as far as your problem is concerned. > > I've attached CurrentDmesg.txt (output from xdiagnose) while filing this bug. > That output provided when this bug occured. For your USB printer, we can see below message, which simply means that the two printers experienced one disconnect/connect event, so some userspace application may not work any more since they need to reopen the device handler. If there are printer daemon or services, I guess that restarting these daemon or services may workaround the problem.

Yes, if you can build kernel, it is helpful to enable CONFIG_USB_DEBUG and post out the 'dmesg' info. But if you can't, I am wondering if we can find why the printer disconnects suddenly.
