https://bugzilla.kernel.org/show_bug.cgi?id=212045 --- Comment #7 from Tomasz Grobelny (tomasz@xxxxxxxxxxxx) --- 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? -- You may reply to this email to add a comment.
