This is a lot better. 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.
