With version 222-1 there is no /lib/udev/rules.d/42-usb-hid-pm.rules
anymore. However, I gave it a try but the bug is not gone.

After SCSI detection it takes ~100 seconds to finish USB HID detection.
That is ten times more than with udev 215-18. So the system is not
unbootable anymore but painful slow booting.

I went back to 215-18 again and the system boots as usually.
