What's the CPU vendor out of curiosity? AMD? Intel? What generation if possible? Trying to gather what controllers are commonly seeing this behavior, i have some ideas to tackle this as well but need to know the issue at scale

[xplanthris-zz]

Intel

[xplanthris-zz]

However an AMD laptop has the same problems

[gus33000]

and the generation of both?

[xplanthris-zz]

5950X for the AMD and Core I7 10510U

[gus33000]

USB-C or USB-A controller? What's the max speed supported on both controllers?

[xplanthris-zz]

USB-A, how do I figure out the max speed part

Yes but this isn't why I am asking above questions here. I am trying to get a repro environment going.

[xplanthris-zz]

i couldnt get the speeds but according to one of the answers there are rates and so
high for the intel laptop
and full for the amd
