This is definitely a USB issue (correct cc's added).  It looks like some
attempted reset finally ...

... leads to disconnection here.

This is all symptomatic of the command SCSI is trying to send never
reaching the device.

Then USB begins again with the same device:

And runs into identical problems.

Most likely, knowing USB, it's either some interface problem, or the
device hung up on a SCSI command it didn't like.  What's the last known
good kernel?  If the usb people don't recognise it, then likely we'll
need a bisection search from there.
