Anyone have any further comment on this one? I've just come crashing
into the same problem - clean install of 14.04 Xubuntu on an MSI
H97M-G43 motherboard, and all is well until I connect my 2x460e and
2x290e tuners. At that point, I can watch the USB devices drop off as
the xHCI subsystem dies.... it's like that scene from Terminator 2 as
the red light slowly fades on my mouse... :-(

... while lan0, sshd and everything non-USB keeps purring on nicely.
I've tried various kernels, all seem to have the same issue (although
I'm yet to try 3.13.3 or 3.13.4 as above, that's on my to-do):

... one of which (the unsigned 3.13.0-39) I compiled myself,
modularising EHCI and xHCI and then blacklisting the latter. Sadly, this
just shut down all my USB ports, which is hardly convenient.
>From what I read, it's a fundamental issue with Linux and USB 3.0, and
the best way to resolve it is to disable xHCI at the BIOS level and then
fall back to EHCI/USB2 throughout. Sadly, the MSI board doesn't support
disabling xHCI, so that's not an option (although buying a different
mobo on which I can disable it - Gigabyte, for example - is looking
increasingly attractive).
Interestingly, the same tuners work perfectly on the same kernel
(3.13.0-39 backported to Precise) on an earlier revision of the same
board (H77MA-G43), so I don't know if it's chipset-related or just
'quirky'.
