    kernel/usb4bsd: Configure the correct bMaxPacketSize for control endpoints.
    
    * Configure the correct bMaxPacketSize for control endpoints before
      requesting the initial complete device descriptor and not as part of
      the subsequent babble error recovery. Babble means that the received
      USB packet was bigger than than configured maximum packet size. This
      only affects enumeration of FULL speed USB devices which use a
      bMaxPacketSize different from 8 bytes. This patch might help fix
      enumeration of USB devices which exhibit USB I/O errors in dmesg
      during boot.
