vexpress-usb mount failed on lava dispatcher

[Naresh Kamboju]

vexpress-usb mount failed on lava dispatcher. due to this reason LAVA jobs failed to complete on vexpress-tc2-benchmark and vexpress-tc2 devices.

This bug is critical for 14.05 release testing.

This almost certainly needs a reboot of the dispatcher. We're getting more of these, so need to look at high quality powered hubs for all production devices.

I think this has a lot to do with the ever increasing number of USB devices
connected to a single dispatcher.

As I'm getting tired of the tc2-benchmark being a SPOF (terrible, terrible
idea there) I suggest we get a small form factor PC, something like the NUC
Alan had at connect, sit it on the shelf next to the tc2 and let it have
it's own dispatcher. No USB hubs, just a straight USB connection from the
device to the dispatcher..

Possibly, but I’d like to explore the powered USB hub solution, just to see if that improves things. I think investigation, rather than ad-hoc solutions would be a better idea.

Agreed - don’t get me started.
