So, I kinda had to give up on that device, had to ship it. No idea what excactly was the problem with that.
I’ve set up a new devive today (basically same computer), did the same routine of setting it up, installing winodws and so on… With that one, capturing went perfectly fine. So basically my problem is somewhat solved by that… In the way that my company can continue their workflow as usual.
I still would like to understand what was going on with that pc… But I can’t do any more test on that one… So I guess we’ll never know…
Thank you guys for helping me
