I suggest adding initcall_debug=1, it'll show how long the usb and other
initcalls take to run. You should see the first usb device driver initcall
take a second or two to run (without the patch). Maybe I'm just badly
affected by having HCDs with 10 ports (of which only 4 are physically
usable...).
