Well, it shows:

[  349.789200] hub 1-0:1.0: port 4 disabled by hub (EMI?), re-enabling...

I guess this about the time when the streaming stops? How does your USB
wiring setup look like and what kind of system is that? Smells like a
hardware issue, to be honest. You could do some stress-testing by
transferring huge amounts of data from one USB storage media to another.
Also try replacing the cables maybe.

I'm Cc'ing the linux-usb list, maybe someone there has an idea.
