USB 3.0 Problems are now unmissable

USB 3.0 Problems are now unmissable

Hi,

I have a new, Asrock Z390-based motherboard running Windows 10 Pro. My TBS5980 now shows tearing MPEG artifacts very often with DVBViewer Pro. I am quite sure that these problems have been created by the new motherboard, since my previous Z170-based old one did not have that. When I switch on the setting to "show delayed images", I can see more of those frames, but with slight offsets. I think that this is a timing problem on the USB part.

I have had similar problems in the past which were caused by DPC latencies. I have looked at the DPC latency checker. All latencies were around 500 microseconds and very constant.

Matter-of-fact is that the new board does not have any USB 2.0 sockets. I have found that the TBS5980 does not support USB 3.0, so these days, that problem becomes unmissable. I have tried an USB 2.0 hub, but the problems did not go away.

Is there a new driver to solve these problems?
