Yes, this is the fundamental problem.

What's the best setting for the random blob of silicon on the end of
your usb plug?  e2fsprogs can't call tech support, even to get bad
answers.

We'd like to help in software, but we can't; we have no reliable way
of knowing most of the necessary details of this class of hardware.
It's not exported in any way.

So unfortunately we are as in the dark as you are in this case.
