No more I/O errors. We still have irregular suspends and resumes, but that's to be expected. More worrying are the spontaneous disconnects. They don't seem to be related to the suspend/resume activity. You can disable suspend for this device entirely by doing: echo on >/sys/bus/usb/devices/2-4/power/control I'm afraid that this won't prevent the device from disconnecting itself, though. This appears to be some sort of hardware bug that can't be fixed in software.
