Hello,

I have logged a request for analysis. We will first need to reproduce it and see what is cutting the USB traffic.

But, as this is the only report of such issue we have had, the analysis is queued and not scheduled.
In the meantime, you may wish to look to see if there is a firmware update for the Surface Dock which might update its internal USB hub firmware as this issue might have been observed with other devices downstream.

Kind regards,
Alban
