sorry for the late reply.
Unfortunately the ASMedia controller is very tricky.
We have been and we still are in contact with ASMEdia to find a solution but as this is not in any way something we can have an impact on, we can just wait.
I appreciate the log files you’ve send, I have forwarded them to our RND and I hope they will get some more insight.
I will come back to you as soon as I know more.
