We have pulled u6 from our production systems because of this very
error. We see it too, mostly when we make a simultaneous call. It
also doesn't happen reliably.
In past posts, I posted the specific version that this came about.
This also seems to only occur with USB adapters, the DS9490R.
We've tested this version in our lab, and it still has the same issue
we reported with p5; specifically, when using a DS-9490 and a bus with
a few temperature sensors, writing 1 to simultaneous/temperature or
simultaneous/voltage returns Error: No such device. This has been
confirmed as working
We get the same problem, if we downgrade to p4 (I think...I don't have
that system in front of me), it works. Go before p4, and it gets
worse for a couple versions. I think p2 is stable (but the python
code has a typo in it on spacing, this goes all the way back to the p0
release).
So yea,
We are seeing variants of this problem; it was introduced in p5; p4
does work more stably in this regard.
