The real problem seems to be some sort of race in usbtmc and the core between URBs being added to an anchor, file I/O being stopped, and URBs being killed or scuttled when the file is flushed.
just to make sure, you think it is failing here: usb_anchor_resume_wakeups(anchor); because we cannot guarantee that the anchor pointer is still valid, unless we refcount anchors, which would make embedding them impossible? Regards Oliver
