Sorry, I try to change patches according to your requests, but sometimes I
overlook something.
Also, it looks like I forgot to add proper header to efikamx-usb.c. Should I

Universal Serial Bus Specification Revision 2.0, chapter 7.1.7.5 Reset
Signaling says: "It is required that resets from root ports have a duration
of at least 50 ms (TDRSTR)."
