Multiple BMD Devices - Issues

PostWed Apr 11, 2018 10:10 pm

I am working on a mobile solution for sport capture, and have hit some issues.
I called BMD support and 'all knowledge of what I was trying to do was disavowed...

Essentially I have
1/ Intensity Shuttle - USB 3
2/ Ultrastudio Mini Thunderbolt 3
3/ ultrastudio Mini Thunderbolt 3
all connected to the same laptop
(HP ZBook 17 G4)
(see image attached)

And it works - sometimes..
It keeps coming up with - the Ultrastudio requires an updated driver.
If i install the driver all of the devices stop working (including the intensity Shuttle), however if I dont update the US HD Mini driver, it seems to work okay.

perhaps someone can shed some light on this, as it works sometimes, but not others..

That is a lot of data going trough a laptop.. ;) I'm even suprised you get it running with 2 Ultra studio HD connected to Thunderbolt.. ;)

Laptops are portable.. But i haven't seen a lot of people getting a stable working setup with 3 capture devices to them.. People have more luck with an external PCI express box connected to thunderbolt and trow a decent Decklink card into it. ;)

Throughput doesn't seem to be an issue, just the drivers issues..

HP ZBook g4 is easily powerful enough to cope if the driver problems can be sorted out.

Interesting, later today I plugged an external usb 3 HDD into the laptop, and although there was no driver change for the HDD, it immediately popped up with the prompt to update the ultrastudio he mini driver.

Interesting update.
If I plug in a aja sdi usb3 capture device with the 2 ultrastudio devices, all three work, if the intensity shuttle is plugged in now the all except the aja disappear.
