Hello,
The Bluetooth of the laptop could only have a play if you were putting the antenna on top of the USB 3.0. As far as I have seen, antennas in laptops have been on the side of the display so far away.
Instead of moving both devices at the same time, I would like to get a minium reproduction setup.
You've seen in previous post as with the cross testing we've excluded the DisplayLink chip or driver as being a root cause.
If we want this resolved, we will need to analyse what is taking place on the USB and we will report this to the manufacturer and other relevant parties.
We've got the equipment necessary, we've got USB experts, and I am fine buying what we need to reproduce, but I don't want to have to buy a house if a table is enough... That's why I would like you to get one thing to change at a time as it we will know what factor causes the problem.
For instance, can you reproduce with just the mouse connected to the D3100 to the laptop. If not, add one thing: a display, or Ethernet. Then we get the minimum failure configuration, and that becomes possible to analyse: we purchase the equipement, set a USB analyser and see what's happening on the bus in both directions.
The reason I am a bit suspicious about the mouse or keyboard being the trigger is that there are millions of the D3100 in use. But offices don't tend to have high DPI mice, and the amount/shape of traffic they create, most likely on USB 2, could have an impact. A dumb keyboard and mouse generate little traffic on USB 2 and all the rest is USB 3. The USB hub/host have to juggle with the two.
Kind regards,
Alban
