- Fix a runtime failure. While usb_control_msg is supposed to return the
actual number of bytes received, the FreeBSD version returns the receiving
buffer size instead. Applications inspecting the returned length for error
checking will fail. My patch is based on this excerpt from FreeBSDs
/usr/src/sys/dev/usb/usb.h.
