No, it also happens on USB2. All testing I did was on 40.
To recap, everything works fine on amd64, my testing was mostly done on arm7, an odroid xu4 to be specific where it seems to work with tthe older SDK but not with the current one. I just did a quick test with a raspberry pi3 where I could not get it to work reliably with either version.
I'll do some more testing on the weekend.
Would you be interested in an image for the odroid or the pi where the problem could be reproduced?
