Sundtek MediaTV Pro (Europe) / "scan no data, failed" with 2 out of 3 tuners

I'm not sure if this is related to the USB 3.0 bug that is described in this bugzilla report https://bugzilla.kernel.org/show_bug.cgi?id=75521
I'm using the following setup:
Because of the known USB 3.0 bug, I enter https://bugzilla.kernel.org/show_bug.cgi?id=75521#c28 this line before starting tvheadend and I do this for all three tuners.
After using tvheadend a while, the MediaTV Pro tuners stop working and tvheadend reports "scan no data, failed". The Digital Home tuner however keeps working. After a reboot of CentOS the whole setup works again for a while.
So now the question; is this behaviour to be expected, keeping the USB 3.0 bug in mind? Is there a logical explanation for the fact the Digital Home tuner keeps working?
I'm using the following setup:
- 2x MediaTV Pro III
- 1x Digital Home http://ecx.images-amazon.com/images/I/41QsVyeH1sL._SS400_.jpg
