The log shows the device just disconnected from the system.  You should
post more of the logfile before the disconnect so we can see if it's an
issue with the USB core.  Did it work with a previous kernel?

It could be that your disk is just dying, and occasionally
disconnecting.  Or you could have a bad cable or a hub that's
introducing noise.  Can you try a different USB cable?
