--- Comment #7 from Tomasz Grobelny (tomasz@grobelny.net) ---
What do you mean by "function driver"? The userspace code that actually opens
the ep0/ep1/ep2 files exposed by functionfs? It works correctly for other
hosts.
I don't have any more data to argue it is dwc2, but still seems like an issue
in kernel USB subsystem.
Another question that might help debugging it: is it the host that should open
the ep2 endpoint? In other words: is it the host that is directly responsible
for lack of any mention of ep2 in dmesg output after the device was
reinitialized?
